I don't know where you found a initWithUTF8String: length: method ... 
not in the GNUstep base library afaik.

The initialiser for use with UTF8 strings expects a nul terminated 
string and has no length argument.
If you have a string with no nul terminator you should create an NSData 
object from it, then use initWithData:encoding:

Apple introduced (in macos 10.3) a new initialiser which would avoid 
this intermediate stage, but it's not in GNUstep yet.
