Line 1,011:
Conversely, when <text> is written using the Latn script, the IETF script subtag, if present, should be Latn.
For the purposes of this test, Latf (Fraktur) and Latg (Gaelic) are considered to be equivalent to Latn because
unicode treats these two scripts as font-specific variants of Latn.
Returns an error message when mismatch detected; nil else.
