* Macros curlx_convert_UTF8_to_tchar(), curlx_convert_tchar_to_UTF8()
* and curlx_unicodefree() main purpose is to minimize the number of
* preprocessor conditional directives needed by code using these
* to differentiate UNICODE from non-UNICODE builds.
*
* In the case of a non-UNICODE build the tchar strings are char strings that
* are duplicated via strdup and remain in whatever the passed in encoding is,
* which is assumed to be UTF-8 but may be other encoding. Therefore the
* significance of the conversion functions is primarily for UNICODE builds.
*
* Allocated memory should be free'd with curlx_unicodefree().
*
* Note: Because these are curlx functions their memory usage is not tracked
* by the curl memory tracker memdebug. You'll notice that curlx function-like
* macros call free and strdup in parentheses, eg (strdup)(ptr), and that's to
* ensure that the curl memdebug override macros do not replace them.
