Well, that depends on the text ;-) Generally speaking, since font
encodings are a workaround for the 256 glyph limitation of tfm files,
most likely you will indeed combine several tfm files with different
encodings into a single font. Not just T1 and TS1, but also other

Context has some tfm font loading code. I only use OpenType fonts.
Maybe you can use code from the LuaTeX wiki as a start:
