You must use UTF-8, see:

I believe all of ISO-8859-1 (Latin 1) is supported in Unicode with code
positions unchanged. The bytes will, of course, be different in a UTF-8
encoded stream.

Note that Microsoft's CP1252 uses codes 0x80--0xBF which aren't in Latin 1
and do require translation to different Unicode code positions, see:
