[SOLVED] TTF True Type Fonts

Hi! English is not my first language, please, excuse me. I had a trouble with TTF: I can't see them with mate font visor, or font forge or even libreoffice. (in mate visor "unable to read the font face file ..."; in fontforge ".._ttf is not a known format (or uses features of that format fontforge does not support, or is so badly corrupted as to be unreadable)") Fonts are in /home/.fonts/ and I can see them in another PC with Manjaro, and in a tablet with android...then, ttf fonts are fine, cos are  the same (copy and paste).  I had this fonts trouble in chimaera, and troubles with mate. All mate's issues gone resolved with an update to Devuan testing (and troubles with Network Manager and WiFi too was resolved), but TTF issues persist. I don't know what can I do, or what I can install or modify to resolve it. And I don't know what can I post to define better my problem. I hope someone understand what I am saying smile... and someone had some idea. Thanks

Re: [SOLVED] TTF True Type Fonts

I put it too in /usr/share/fonts/ doing fc-cache -f -v, but new fonts are not recognized, even if they are recognized in other dispositives.I need these particular fonts for my work... is not trivial.

Re: [SOLVED] TTF True Type Fonts

Does the font show up if you grep for the font.

Try this.

fc-list | grep "YOUR FONT NAME.TTF"

Re: [SOLVED] TTF True Type Fonts

Well, I copy new fonts to:

TTF: /usr/share/fonts/truetype
OTF: /usr/share/fonts/opentype
ATM: /usr/share/fonts/type1, not really supported any more nowadays

and I create a new directory for them below that paths. Do the copy with root privileges, and make sure the directory has 755 as octal rights and the fonts have 644 as octal rights.

Works fine.

Possibly one way to begin to diagnose your situation is from the command-line. If you have mlocate installed (to quickly locate files) and either FireFox and/or Thunderbird installed then you will be able to locate this specific TTF font:

$ file /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf
/usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf: TrueType Font data, 17 tables, 1st "COLR", 12 names, Macintosh, type 1 string

That should help to begin to help discover exactly what your system thinks any particular ttf file is.

One final other common source is mscorefonts and/or fonts-liberation:

$ apt search fonts-liberation
Sorting... Done
Full Text Search... Done
fonts-liberation/stable,now 1:1.07.4-11 all [installed]
  Fonts with the same metrics as Times, Arial and Courier

fonts-liberation2/stable,now 2.1.3-1 all [installed]
  Fonts with the same metrics as Times, Arial and Courier (v2)

ttf-mscorefonts-installer/stable,now 3.8 all [installed]
  Installer for Microsoft TrueType core fonts

$ file /usr/share/fonts/truetype/msttcorefonts/Arial.ttf
/usr/share/fonts/truetype/msttcorefonts/Arial.ttf: TrueType Font data, digitally signed, 23 tables, 1st "DSIG", 70 names, Unicode, Typeface \251 The Monotype Corporation plc. Data \251 The Monotype Corporation plc/Type Solution

Thank you for answer.  Path and privileges are the same here, but nothing happen.

Thank you for answer.

AHA6.ttf is the font that I need. I had done your suggestion:

 root@devuan:/home/gaurial# file /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf
/usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf: TrueType Font data, 17 tables, 1st "COLR", 12 names, Macintosh, type 1 string

root@devuan:/home/gaurial# file /usr/share/fonts/truetype/aha/AHA6.ttf
/usr/share/fonts/truetype/aha/AHA6.ttf: data

Now, AHA6.ttf was created for me with fontforge. But I used for years... problem is now with a fresh install.

If I put DejaVuSans.ttf in /home...local/font/ and I do fc-cache -f -v (as superusser and normal user) I had:

 /home/gaurial/.local/share/fonts: caching, new cache contents: 0 fonts, 0 dirs

and if I do a file I had:

root@devuan:/home/gaurial# file /home/gaurial/.local/share/fonts/DejaVuSans.ttf
/home/gaurial/.local/share/fonts/DejaVuSans.ttf: data

... the same thing as with AHA6.ttf ...

...but if I do a file with the same font DejaVuSans.ttf installed with apt I had:

 root@devuan:/home/gaurial# file /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf
/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf: TrueType Font data, 20 tables, 1st "FFTM", 26 names, Macintosh

Then is not a problem with my font.
May be directories issue? no. If I put a font (not created for me) ImperiumSerif.ttf In /usr/share/fonts/truetype/Imperium and I do fc-cache -f -v as SU, I had:

/usr/share/fonts/truetype/Imperium: caching, new cache contents: 0 fonts, 0 dirs

and if I do a file I had:

root@devuan:/home/gaurial# file /usr/share/fonts/truetype/Imperium/ImperiumSerif.ttf
/usr/share/fonts/truetype/Imperium/ImperiumSerif.ttf: data

... the same thing as with AHA6.ttf

Finally, Typographic viewer of Mate is not able to see ImperiumSerif.ttf in /home/... neither /user/...  as with AHA6.ttf
and Fontforge open (recognize) /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf installed with apt, but not  /home/gaurial/.local/share/fonts/DejaVuSans.ttf .

Re: [SOLVED] TTF True Type Fonts

Please use [ code ] ... [/ code] tags to quote terminal-results (as below) (keeps the text in this window small). You would also be well advised to use your computer as an ordinary user rather than the root user. Switch to the root user only when you have some extensive admin to do that actually *requires* root to work (updating the system is such a requirement).

That is a proper ttf font …

# file /usr/share/fonts/truetype/aha/AHA6.ttf
/usr/share/fonts/truetype/aha/AHA6.ttf: data

… and that is most unlikely to be such a font. Here is one way to check:–

$ strings /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf | wc -l
28319

(28,319 lines of text-strings - that is what a ttf font should look like)

Here is what the top of the file looks like (you can also change the 'head' to 'less' (no quotes) to examine the whole file):–

$ strings /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf | head
COLR
QlCPAL
FFTM
GDEF
GSUBq
OS/24
`cmap%=

Now an examination using a hex-viewer; look at the first 12-bytes to see the magic-signature for a ttf font (ALL ttf-fonts should look something like this in the 1st 12 bytes):

$ hexdump -C /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf | head

You can now examine both TwemojiMozilla.ttf & AHA6.ttf on your own machine to discover whether these rogue fonts are actually fonts at all.

Re: [SOLVED] TTF True Type Fonts

 # strings /usr/share/fonts/truetype/aha/AHA6.ttf | wc -l

# strings /usr/share/fonts/truetype/Imperium/ImperiumSerif.ttf | wc -l
1083
# strings /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf | wc -l
28319

yes, number is inferior, but why I can use it in other dispositives, (another pc, notebook and tablet -with linux-deploy+debian 8) ?

and why ...

 # strings /home/gaurial/.local/share/fonts/DejaVuSans.ttf | wc -l
24562

... gives a proper number, but the font is not recognized, if is not installed with apt?

May be something is wrong in the way of my system recongize the fonts, and not in the fonts themselves.

Now i will go hexdump

0000090 7507 696e 4631 4433 7507 696e 4631 4533

In my system some fonts don't have ...

but are recognized and working. May be somethings related with fonts management is wrong.

Re: [SOLVED] TTF True Type Fonts

And when I try to have a preview of several fonts with mate typographic viewer I had this error (from xsession-errors) in all tested fonts:

Re: [SOLVED] TTF True Type Fonts

You have not included the full command for hexdump to get the correct result (it is hexdump -C). However, to make life simple for yourself use the shortcut hd (I only just discovered that just now - it is also hexdump).

If you look at this Wiki page for File Signatures you will find that the magic signature for ttf is 00 01 00 00 00. Therefore:

$ hd /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf | head
00000000  00 01 00 00 00 11 01 00  00 04 00 10 43 4f 4c 52  |............COLR|
00000010  9b 59 1b ad 00 13 22 f8  00 02 51 6c 43 50 41 4c  |.Y...."...QlCPAL|
00000020  99 fd 98 85 00 15 74 64  00 00 0f ea 46 46 54 4d  |......td....FFTM|
00000030  94 98 f7 41 00 15 84 50  00 00 00 1c 47 44 45 46  |...A...P....GDEF|
00000040  00 27 34 59 00 15 84 6c  00 00 00 1e 47 53 55 42  |.'4Y...l....GSUB|
00000050  71 92 ee f7 00 15 84 8c  00 00 6c 80 4f 53 2f 32  |q.........l.OS/2|
00000060  34 c3 0a 83 00 00 01 98  00 00 00 60 63 6d 61 70  |4..........`cmap|
00000070  25 3d b7 6c 00 00 6a a8  00 00 0b fa 63 76 74 20  |%=.l..j.....cvt |
00000080  00 11 01 44 00 00 76 a4  00 00 00 04 67 61 73 70  |...D..v.....gasp|
00000090  ff ff 00 03 00 13 22 f0  00 00 00 08 67 6c 79 66  |......".....glyf|

and you will spot the magic signature starting at '00000000'. If *your* ttf files do not start with this signature (which AHA6.ttf does not), then they will not be recognised by the system as TTF font files. My best guess then is that something within the way that you are processing them is shafting them.

There is a helpful Step-by-Step install TTF fonts on Linux page if you need help on that.

Update: spel-check

Re: [SOLVED] TTF True Type Fonts

Thank you Alexkemp. Finally solved. Your suggestions made think in a possible corruption of files inside a flash drive (fresh install... then I moved fonts to a new PC through a flash drive)... and yes... files were corrupted. When I moved them with another flash drive, system recognized AHA6.ttf and all other fonts. Thank you for your guide and time... I learned some new things, commands and how to post properly from you. Thanks again.
Pd: You was right .... system is fine and fonts were bad smile
