Re: [fpc-pascal] cross platform version of IsCharAlpha()
The problem with such function is that it requires a lot of data to be used on a non ANSI table. and you can not use in a unicode implementation the Char type, because a char can be more then one byte.

Re: [fpc-pascal] cross platform version of IsCharAlpha()
Because it depends on the code page of the system you are using at the moment you parse the char.

Add a new entry to the widestring manager, add a implementation to sysutils using the widestring manager. Implement it in the cwstrings for unix and sysutils directly for windows, for unix you can use iswalpha: http://opengroup.org/onlinepubs/007908775/xsh/iswalpha.html Create a test and submit a patch :) ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
