get the characters available in TrueType with PHP

Question

How do I get a list of all characters available in the TrueType font? using PHP.

Answer 1

PHP does not seem to have any extension that works directly with FreeType, the reigning open source library to deal with TrueType fonts.

You may have to shell out to another language with an appropriate library, like Perl's Font::FreeType::Glyph, which will let you ask each font whether it has a representation of a particular glyph.

In the alternative, you could write the proper PHP extension directly in C.
