Testing Instructions:

Hide

1/ install several language packs with different alphabets - de, zh_cn, ja, ar for example
2/ open http://yourserver.local/moodle/lib/tests/other/pdflibtestpage.php and try
different font families by modifying the URL (use some of the font families listed in the pdf itself) and verify there are no errors - missing chars are OK because not all fonts support all languages
3/ download the fonts zip from http://sourceforge.net/projects/tcpdf/files/ and extract it into your dataroot/fonts/ directory
4/ try the test page again - verify there are a lot more fonts, try several fonts including the new ones again
5/ install certificate module and verify there are no regressions when printing both embedded and non-embedded certificates
6/ hack mod/certificate/type/A4_embedded/certificate.php to use dejavusans and verify it still works

Description

When the tcpdf library was last upgraded, in ~~MDL-40107~~, it introduced a bug that prevents the default font folder from being replaced by a fonts folder in dataroot. This prevents using custom / additional fonts in custom certificate types (unless you place the font files in lib/tcpdf/fonts).

pdflib.php defines the pdf class which overides the TCPDF class. Support for custom font folders is introduce by overiding the _getfontpath() member function. However in the new version of TCPDF this function has been moved into a new class TCPDF_FONTS causing the Moodle version of _getfontpath() to no longer be called.

I haven't confirmed that Moodle 2.5 works. But I had M22, M26, and M27 test sites that I tested the bug against. M22 worked, but M26 and M27 sites were both broken.
