The qstrtoull() function returns ulonglong, not int, so we'd be
incorrectly detecting 0x1'0000'0814 as NyNorsk. Paranoia? Sure.
Fix by using auto to hold the result.
As a drive-by, make the QByteArray const so .data() doesn't
attempt to detach(), and shorten a long variable name to stay
within line-length limitations.
Pick-to: 6.4 6.3 6.2
