Polybios can use TrueType fonts. There are two types of TrueType fonts: The first format, which uses the ".ttf" extension, contains
only one font in its file. The second format, which uses the ".ttc" extension, contains multiple fonts in its file. That is
why doc:LoadTTFont() has a parameter which is used to specify the index of the font to load. If the additional parameter embedding
is set to True when invoking doc:LoadTTFont(), the subset of the font is embedded into the PDF file. If not, only the marix data
is stored in the PDF file. In this case a viewer application may use an alternative font if it cannot find the font.
Here is an example:
fontname = doc:LoadTTFont("arial.ttf", True)
hfont = doc:GetFont(fontname, "CP1250")
page:SetFontAndSize(hfont, 10.5)

Note that Polybios can use only TrueType fonts which have a Unicode cmap and one of the following tables: "OS/2", "cmap", "cvt ", "fpgm", "glyf", "head", "hhea", "hmtx", "loca", "maxp", "name", "post", "prep".
