The old version uses mbstowcs() to calculate the buffer length while the new version is using a new function called calcRequiredSize(const char* const srcText). Inside calcRequiredSize(), mblen() is being used to get max character size: unsigned int Win32LCPTranscoder::calcRequiredSize(const char* const srcText) { if (!srcText) return 0; unsigned charLen = ::mblen(srcText, MB_CUR_MAX); if (charLen == -1) return 0; else if (charLen != 0) charLen = strlen(srcText)/charLen; if (charLen == -1) return 0; return charLen; } I found that if the source string starts with multibyte character, "transcode" in 2_3_0 will always fail. I tried calling setlocale(LC_ALL, "") before transcode. It did change MB_CUR_MAX from 1 to 2. But mblen continued to return -1 despite of my effort. The 2_1_0 version of transcode uses mbstowcs() and it's working fine. Is that a bug of 2_3_0 or am I missing something? My environment is: Win2K Professional/VC++.Net2002 Standard (Both are Japanese Edition) Thanks for your attention. regards Lei --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
