Starting with version 4 Coin3D uses UTF8 encoded strings. However, there is no method exposed by the SbString class that encodes a wide character string to UTF8. Also the included utility function cc_string_utf8_encode() only converts single characters and does not handle platform specific encoding of wide character strings (Linux: utf32, Windows: utf16).
In my opinion it would be very useful if the SbString class accepts also wide character strings, taking care of the conversion to UTF8. Please comment on this proposal. Would it be safe to assume that all targeted compilers support the wchar_t type now? I could implement this functionality if there are no concerns.
