       Resolution: Fixed
    Fix Version/s: 3.0.1

I believe this has been fixed in 3.0.1.

> We try to migrate some code to MIPS paltform, and got a failer while parsing an xml file using xerces-c++.
> So we check the code and found that when a LocalFileInputSource is constructed, the file name is composed as following:
>         XMLString::copyString(fullDir, curDir);
>         fullDir[curDirLen] = chForwardSlash;
>         XMLString::copyString(&fullDir[curDirLen+1], filePath);
> and chForwardSlash is define as following:         
>         const XMLCh chForwardSlash          = 0x2F;
> In our MIPS platform, this variant is in big-endian, but curDir and filePath are in little-endian, so we got a wrong fullDir.
> The reason why curDir and filePath are in little-endian is that IconvGNUTranscoder only use little-endian transecoder:
> static const IconvGNUEncoding    gIconvGNUEncodings[] = {
>     { "UCS-2LE",        2,    LITTLE_ENDIAN },
>     { "ucs-2-internal",        2,    LITTLE_ENDIAN },
>     { NULL, 0,    0 }
> };
> When we add  { "UCS-2BE",        2,    BIG_ENDIAN } to gIconvGNUEncodings, everything is OK.
> Is this an intended behavior or a bug?
