[I'm talking about FreeType 2]

FreeType doesn't know anything about character sets.  There are two
methods to access glyphs: directly and with an encoding to map
character codes to glyph indices.  To use the former, simply specify
the glyph index to FT_Load_Glyph().  For the latter, FreeType
predefines some encodings; please read the documentation of
FT_Encoding.  With MS Windows you should normally use
ft_encoding_unicode with FT_Select_Charmap().  A call to
FT_Get_Char_Index() converts the input character code to a the glyph
index which can then be fed into FT_Load_Glyph().
