> Project: Log4cxx
> Issue Type: Bug

> Affects Versions: 0.10.0
> Environment: Windows XP SP2
> VC8.0SP1
> Reporter: Starwalker
> Assignee: Thorsten Schöning
> Priority: Major
>
> Load properties file fails when calling PropertyConfigurator::configure using
> a MBCS string which type is char * or std::string and contains multibyte
> characters, such as Chinese characters.
> Analyse
> When calling PropertyConfigurator::configure using a MBCS string which type
> is char * or std::string, the constructor of File will call
> Transcoder::decode to convert MBCS string to DBCS string. When meets the byte
> which is greater than or equal to 0x80, the function will call
> MbstowcsCharsetDecoder::decode to process the following characters. But there
> is an error in MbstowcsCharsetDecoder::decode when calculating the offset
> after calling mbsrtowcs.
> size_t converted = mbsrtowcs(buf, // This function returns the number
> of wide characters, maybe not equal to the number of the bytes of multibyte
> characters
> &src,
> requested,
> &mbstate);
> if (converted == (size_t) -1) {
> stat = APR_BADARG;
> in.position(src - in.data());
> break;
> } else {
> stat = append(out, buf);
> in.position(in.position() + converted); // Here, the number of the
> bytes of multibyte characters should be added, not the number of wide
> characters
> }
> The path "D:\Temp\中文文件夹\STC\Config\Log.properties" becomes
> "D:\Temp\中文文件夹\STC\Config\Log.propertiesrties" after convertion.
> There are 10 bytes for the 5 Chinese characters, but only 5 wide characters.
> Because the error above, last 5 characters repeated.
