Re: [fpc-devel] ansistrings and widestrings

[Alexey Barkovoy]

Well functions are called ANSI to unicode and vice versa. ANSI is always single 
byte; by unicode people usually refer to utf16, not multibyte encoding and both 
Delphi and FPC define WideString as double byte strings. So semantically 
functions do that is required. IMHO then assigning widestring to ansistring 
noone should expect multibyte encoded result. Then you need utf-8 you should 
call special functions.

ok i see a MAJOR problem with the semantics of those functions.
they assume that one widechar is equivilent to one ansichar (that is the
source count of widechars will equal the destination count of ansichars or
the source count of widechars will equal the destination count of
ansichars).
this is simply not the case for many encodings. (utf-8 sjis euc to name just
a few)
