'language' is an arbitrary IETF BCP 47 language identifier such
as 'en', 'de-CH', 'de-AT-1901', or 'fa-Latn'. When possible, we
create a Macintosh NameRecord that is understood by old applications
(platform ID 1 and an old-style Macintosh language enum). If this
is not possible, we create a Unicode NameRecord (platform ID 0)
whose language points to the font’s 'ltag' table. The latter
can encode any string in any language, but legacy applications
might not recognize the format (in which case they will ignore
those names).
'font' should be the TTFont for which you want to create a name.
If 'font' is None, we only return NameRecords for legacy Macintosh;
in that case, the result will be None for names that need to
be encoded with an 'ltag' table.
See the section “The language identifier” in Apple’s specification:
