* Export parser data (date format, digits, timezone names, and
messages for weekday/month names) converted to language variants
* Update the parsers to try matching using every variant, in case
the page is displayed in non-default variant (and to avoid
problems with incomplete variant conversion)
Bug: T259818
Change-Id: I04d73992cd31ce06fa79f87df0c0a53d7efc3c58
The PHP code incorrectly assumed that the digits are single-byte in
UTF-8, which is never the case (except for 0-9).
The JS code worked correctly because it uses UTF-16 strings, so the
bug would only affect non-BMP digits there. This was noted in a TODO
comment, but we overlooked it when reimplementing in PHP.
Instead of a string of 10 characters, use an array of 10
single-character strings.
