Ahem. Unicode *IS* UTF-8, UTF-16 and UCS-2. For instance, codepoint U+4321 has the value (hex) 4321, which is defined as its Unicode value. This is the same in any encoding. So I'm not sure what you want. If the C routines at http://www.unicode.org/Public/PROGRAMS/CVTUTF/ don't do it for you, which conversion do you need? LE byte order to BE and back? Canonical decomposing? Fallback character substitutions? BOM insertion? What?
Yes I agree to what you are saying above. Let em explain what I want.
Character U+4321 is the unicode code-point but to store this character into a file we need to use a certain encoding format.
e.g. There must be some algorithm to find *the sequence of bytes* that represent this character into *UTF8 encoding*. Similar algorithms must be there for UTF16 and UCS2 encodings, I want C implementation of such algorithms.
Thanks, ~ K.
