[fpc-pascal] Widestrings length and character iteration

[Christos Chryssochoidis]

Hi,

Are there any rtl functions to compute the length (in characters) of  
a widestring and to iterate over its characters?
  In my system (Mac OS X/fpc 2.1.3), a widestring is implemented as a  
UTF-8 encoded string, as I found out.

Thanks
