Jonas Jenwald dfe9015a43 Convert uniXXXX glyph names to proper ones when building the charCodeToGlyphId map for TrueType fonts (bug 1132849, issue 6893, issue 6894) ...

This patch adds a `getUnicodeForGlyph` helper function, which is used to recover Unicode values for non-standard glyph names.

Some PDF generators, e.g. Scribus PDF, use improper `uniXXXX` glyph names which breaks the glyph mapping. We can avoid this by converting them to "standard" glyph names instead.

Fixes 6893.
