Jspdf: Embedded TTF Fonts Not Working when indexToLocFormat is 0 (SHORT)

[lezcuff]

I am using the latest version of jsPDF: 1.4.1
I have also tried using jspdf.debug.js

I have been able to get the basic example to work with the sample font.
however, i have not been able to inject courier prime into the pdf

Steps to reproduce

• Download Courier Prime from http://dimkanovikov.pro/courierprime/
• convert to base64
• open the working basic example code
• replace sample font string with the bas64 encoded string
• print a sequence of cyrillic letters
• save PDF
• open PDF

BUGGY RESULT: lots of exclamation marks

• print a sequence of english text
• save PDF
• open PDF

BUGGY RESULT: some # signs

Similarly, I have had no success embedding

I did a little more digging into the font files themselves.
For the working sample font, the indexToLocFormat is 1 [Meaning Long Offsets (32)] whereas for the two fonts which do not load, the indexToLocFormat is 0 [meaning Short Offset(16)]

That might be the issue.

[lezcuff]

I have confirmed with several fonts that TTF fonts which have indexToLocFormat 1 will display whereas those with indexToLocFormat0 do not display.

Here's a bit of perl which will dump out the TTF headers:
use strict;
use warnings;
use Font::TTF::Font;
use Font::TTF::Dumper;
die "Provide One Argument: Filename" if !$ARGV[0];
my $font = Font::TTF::Font->open($ARGV[0]);
print ttfdump($font->{'head'}, 'head');
