valid BCP47 script variants (only because MediaWiki still does not | |||
define automatic transliterators for them, e.g. "en-dsrt" or | |||
"fr-brai" for French transliteration in Braille), and country variants, | |||

translations, such as zh-cn, also useful for legacy codes). | |||
We want to avoid matching subpagenames containing any uppercase letter, | |||
(even if they are considered valid in BCP 47, in which they are | |||
case-insensitive; they are not "SupportedLanguages" for MediaWiki, so | |||
they are not "KnownLanguageTags" for MediaWiki). | |||
To be more restrictive, we exclude any character that is not | |||
ASCII and not a lowercase letter, minus-hyphen, or digit, and any code | |||
that does not start by a letter or does not finish by a letter or digit. | |||
of that has more than 8 characters between hyphens, or has two hyphens. | |||
