getting a list of all font elements by font family name

zentara has asked for the wisdom of the Perl Monks concerning the following question:

Ok, I'm overwhelmed by all the scripts and unicode information, and I just need a headstart on this.

What I want to do, is get a list of all the hex numbers of a font family, namely the Symbola font collection, but the family name can be generalized.

For instance, this code gives me the descriptive name of the unicode element 0x1F42A, from the Symbola font collection.

#!/usr/bin/perl
use warnings;
use strict;
use charnames();
print charnames::viacode(0x1F42A); # prints "DROMEDARY CAMEL"
[download]

What I am looking for is a way to get all those hex numbers which Symbola provides. How do I dump Symbola to a list of hex numbers?

Thanks, you are saving me a mind-boggle if you know the answer. :-)

For instance, this code gives me the descriptive name of the unicode element 0x1F42A, from the Symbola font collection. Actually, that code gives you the Unicode name for 0x1F42A. `charnames::viacode` is unaware of fonts. Now, following your link and following a link in there gets me the zip file. Unzipping the archive, I find a file called Symbola605.txt. In there, I find a line: "Character repertoire of Symbola", followed by a long list of characters. I expect your answer can be found in this file. And ultimately in the file Symbola605.ttf, but that requires knowledge of the ttf format - knowledge I do not have.	[reply]

Thanks for your input. I did find Font-TTF and Font-TTF-Scripts and hope to be able to figure that mess of scripts out. I'm not really a human, but I play one on earth. Old Perl Programmer Haiku ................... flash japh	[reply]

Googling gives me the answer to use Font::TTF::Name but the docs are hard to figure out. However I did get some results with the script ttfwidth.pl from the Examples directory of Font-TTF-Scripts, which gave output like `$ ./ttfwidth.pl -u Symbola605.ttf There are 6796 glyphs font mapping Microsoft id = 3, encoding = 1 (encoding => UGL coding) Unicode, Glyph, AdvWidth, LSdBearing, Xmin, Xmax, Ymin, Ymax, XCentre 0x0020,3,512,0,0,0,0,0,512 0x0021,10,682,229,229,453,0,1466,341 0x0022,11,809,108,108,701,771,1339,404 0x0023,12,1024,39,39,985,-121,1265,512 0x0024,13,964,108,108,854,-108,1446,483 0x0025,14,1662,50,50,1612,-134,1578,831 0x0026,15,1593,95,95,1498,-45,1466,796 ...etc ...etc` [download] and I did have some good results with `#!/usr/bin/perl use warnings; use strict; use Font::TTF::Font; my $font = shift \|\| "./Symbola605.ttf"; my $f=Font::TTF::Font->open($font) or die "$!\n";; my @out = @{$f->{'post'}->read->{'VAL'}}; #print "@out\n"; my @unihex = grep{/^u[\d+]/} @out; print "@unihex\n";` [download] But my head is starting to spin now, and I think I will set it aside for awhile, until unicode support gets better. Even the app gucharmap fails to display all the glyphs, even though my Tk program can. I'm not really a human, but I play one on earth.

Hi, thanks for that command string, but on my Slackware system, even though I have the Symbola font installed and is working, it dosn't show up in the xlsfonts output. Maybe it's because I don't have a font server running? Oops, I see I need to take the name out of /usr/share/fonts/truetype/fontdir I'm not really a human, but I play one on earth.

What I did with the `.ttf` from that zip: `$ chdir ~/.fonts $ mv /tmp/Symbola605.ttf . $ mkfontscale $ mkfontdir $ fc-cache $ sudo /etc/init.d/xfs restart` [download] And yes, I have my `~/.fonts` directory in the font server list (`/etc/X11/fs/config`).
