Hi Leonard (PDF Sage) and other PDF Sages :)

I am almost finish the font subset. Now, I can subset the font of MS Gothics, however, it only works for characters with font size 18 and above. Any characters with font size that less than 18 will be translated to another characters.

For instance, characters: "a", "b", "c"
For font size 18 and above, those characters displayed perfectly. For the font size below 18, the character has been displayed as: "!", ""(quote)", "#". (I am using notepad to test the font)

I look at the documentation again and I suspect the problem is something to do with the font instruction tables (table cvt, fpgm and prep). But I do not know how to subset this value out for specific glyph (eg. Glyph "a").

I also do not understand about the concept of maxFunctionDefs and maxInstructionDefs in table maxp. Where are these functions and instructions being defined?

Any help from PDF Sages (especially Leonard) will be greatly appreciated.

Cheers :)
