extracts and returns IETF language tag parts:
primary language subtag (required) - 2 or 3 character IANA language code
script subtag - four character IANA script code
region subtag - two-letter or three digit IANA region code
variant subtag - four digit or 5-8 alnum variant code
in any one of these forms
lang lang-variant
lang-script lang-script-variant
lang-region lang-region-variant
lang-script-region lang-script-region-variant
each of lang, script, region, and variant, when used, must be valid
returns four values. Valid parts are returned as themselves; omitted parts are returned as empty strings, invalid
parts are returned as nil.

are listed in the {{transl}} switches they are included in the data tables. The script parameter is introduced
at {{Language with name and transliteration}}. If |script= is set, this function uses it in preference to code.

This function checks the content of args.text and returns empty string if nothing is amiss else it returns an
error message. The tests are for empty or missing text and for improper or disallowed use of apostrophe markup.
Italic rendering is controlled by the |italic= template parameter so italic markup should never appear in args.text
either as ''itself''' or as '''''bold italic'''''.
Also protects single leading and trailing single quote marks from being converted to bold by the addition of
adjacent italic markup.
