curlx_convert_wchar_to_UTF8 must be freed by curlx_unicodefree, but prior to this change some uses mistakenly called free. I've reviewed all other uses of curlx_convert_wchar_to_UTF8 and curlx_convert_UTF8_to_wchar. Ref: https://github.com/curl/curl/commit/1d5d0ae Closes https://github.com/curl/curl/pull/8521
