Yes, you don't need to use encoding manager class for \mac support.

The only safe way to check it is
iconv_open("charsetname","charsetname")
If return value is (iconv_t)(-1), then that charset is not supported.
I think UT_Wctomb and UT_Mbtowc are rather safe to use to the point that AW
won't crash if iconv doesn't support some encoding and it's selected as
destination or source charset for them - so I don't think you should worry
about availability of support for charset.
