If by "Unicode format" you mean "in UTF-16 format", i.e. with (at least) 
two bytes for every character, that's not going to be acceptable to a 
lot of us - UN*X systems that support Unicode tend to use, and support, 
UTF-8 format; I don't know whether *any* UN*X compilers would support 
UTF-16 format.  (In addition, some UN*X systems might be using older 
character sets, such as ISO Latin 1.)
