[H-GEN] awk and unicode on mac osx (bsd)

[johannes at paradise.net.nz]

Perhaps, this was asked before, however, googling does not reveal too 
much though.

Some time ago I  wrote a bunch of scripts under linux to filter ad 
content in e-mail. Works just fine by piping e-mail through awk 
scripts. Now I want to use the same scripting principle under bsd on 
osx and had to find that e-mail is kept in unicode.

Does anyone know how to process unicode (e.g. utf_8) instead of plane 
text with awk?

Cheers
