Under Windows, if you are using language 'fr_FR' , encoding code page
is 'CP1252',

   http://en.wikipedia.org/wiki/Windows-1252

A  Russian  character  like 'Љ' can not  map  to system  allowable
character under your 'fr_FR'
environment.

For Chinese Windows with  'CP950' (Chinese-traditional
http://www.microsoft.com/globaldev/reference/dbcs/950.mspx ) or
'CP936' ( Chinese-simpified
http://www.microsoft.com/globaldev/reference/dbcs/936.mspx)
character 'Љ' also is not  allowable according to the character
mapping table.

Only Russian Windows with code page 'CP1251'
(http://en.wikipedia.org/wiki/CP1251) can accept  character 'Љ' .

For the same reason, if you are going to test Chinese Windows, you can
only execute the chinese part of the test script and should bypass
other parts,
-------------------------this part only for Chinese Windows
----------------------
specialName='中文' ;     //  for CP950, BIG5,zh_TW, zh_TW.utf-8, zh_CN,zh_CN.utf-8
setenv('env',specialName);
if getenv('env') <> specialName then pause, end
----------------------------------------------

Right now, I use static buffers  for the reason of converting speed.
And I avoid to dynamically allocate memories because that may
complicate things.

I was thinking once to create a C++ class  to store the converting strings.

Yes , I myself was not satisfied about this limitation and was looking
for a better alternative. Do you have any suggestion ?
