1018805 - text-transform: lowercase CSS directive is broken for Irish language text

Status: RESOLVED FIXED

(Core :: Internationalization, defect)

Description

[Kevin Scannell]

Attachment: Lots of test cases; A's should lowercase to B's

This is a companion to bug 1014639, which deals with uppercasing.  Irish has a couple of unusual rules for lowercasing.  For example, "An tAthair" should become "an t-athair" (with an inserted hyphen) when rendered in lowercase.

Here are the rules: convert every letter to lowercase as usual, except if a lowercase n or t appears at the beginning of a word, followed by an uppercase vowel (A,E,I,O,U,Á,É,Í,Ó,Ú).  In this case, insert a hyphen between the n/t and the vowel after lowercasing.  In the notation of bug 1014639:

t{V} -> t-{v}
n{V} -> n-{v}
