Which character set to choose when compiling a c++ dll

Question

Could someone give some info regarding the different character sets within visual studio's project properties sheets.

The options are:
None
Unicode
Multi byte

I would like to make an informed decision as to which to choose.
Thanks.

Answer 1

All new software should be Unicode enabled. For Windows apps that means the UTF-16 character set, and for pretty much everyone else UTF-8 is often the best choice. The other character set choices in Windows programming should only be used for compatibility with older apps. They do not support the same range of characters as Unicode.
