Hi Everyone,

Can anyone please help with the following?  

1.  Any example of the source code for a generic Unicode app?  The 
reason for requesting this is the question in 2 below.

2. A set of Unicode tables. If I have an international app, does anyone =

have any thoughts on how to load and map the tables? Should I table 
lookup the whole table or be locale-specific?  Is that possible? I 
believe I have to keep the whole table available due to global nature 
of the app.  One of my concern is performance impact due to the size of =

the table.  My app needs to map data to Unicode. 

Any help would be greatly appreciated.

Thanks,
Smita

Smita, this is Jean-Baptiste, 

1) Dealing with your first problem, I give you some places at the end of the message.
In http://www.microsoft.com/globaldev/gbl-gen/codesets/charsets.htm, retrieve two samples.
Warning: They are not exhaustive, can't be compiled but can help with the WideChartomultibyte/multibytetowideChar samples.

2) If I understand your question you wonder if it is possible to "load" only the part of the table that you need.
This depend on the system you use, on Windows NT or PLAN9 (new AT&T Bell system) UNICODE is inside the system. Files coded with UNICODE can be processed with system calls without doind anything. On Windows 3.1, 95 you'll havw to use calls such as WideChartomultibyte. On Unix you'll have most of the time to load a table and perform the conversion.
It's up to you to create a table with the full UNICODE encoding or just the codes you need, but be carefull, if one day you retrieve or a user fill a data that is not in the table, you'll crash !
