Comment:

 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).
