An encapsulation of a font; i.e.
a set of glyphs that may be assembled together by a TextNode to represent a string of text.
This is just an abstract interface; see StaticTextFont or DynamicTextFont for an actual implementation.
Definition at line 36 of file textFont.h.
Returns a special glyph that can be used as a placeholder for any character not in the font.
Note that it is not guaranteed that a font will return this particular glyph for a missing character (it may return a glyph of its own devising instead).
Also note that even if a particular accented letter is missing from the font, Panda may still be able to render a suitable replacement by composing different glyphs together to simulate accent marks; this happens automatically behind the scenes.
