I find that getting Unicode support in my cross-platform apps a real pain in the butt.
I need strings that can go from C code, to a database, to a Java application and into a Perl module. Each of these use a different Unicode encodings (UTF8, UTF16) or some other code page. The biggest thing that I need is a cross-platform way of doing conversions.
What kind of tools, libraries or techniques do people use to make handling these things easier?
