/* auto-detect the character encoding, to be able to parse XCSoar
6.0 task files */

if (reader.error())
return false;
long size = reader.size();
if (size > 65536)
return false;
else if (size < 0)

buffer.reserve(size);
const TCHAR *line;
while ((line = reader.read()) != NULL) {
if (buffer.length() > 65536)
/* too long */
return false;
