In [changeset:"53754" 53754]:
{{{
#!CommitTicketReference repository="" revision="53754"
Formatting: Normalize to Unicode NFC encoding before converting accent
characters in `remove_accents()`.
This changeset adds Unicode sequence normalization from NFD to NFC, via
the `normalizer_normalize()` PHP function which is available with the
recommended `intl` PHP extension.
This fixes an issue where NFD characters were not properly sanitized. It
also provides a unit test for NFD sequences (alternate Unicode
representations of the same characters).
