modify m_encoding, not m_name, in wxCSConv::CreateConvIfNeeded() if we don't have either (as is the case with wxConvLocal); this fixes an infinite recursion in wxMac after the latest changes as wxLocale::GetSystemEncodingName() there returned empty (and not NULL) string which resulted in call to wxFontMapperBase::CharsetToEncoding() and reentrancy into wxConvLocal
