Follows-up I301f471f86ba2. For ease of navigation, move Converter subclasses to a group called "Languages", which for documentation purposes is a subgroup of "Language". The next commit does the same for Messages* files, and Language subclasses (done separately for ease of review). Change-Id: If1cef9aa15f536ebaedd4477ad7453426e7f3b85

/**
|
||
* Turkish (Türkçe)
|
||
*
|
||
* The Turkish language, like other Turkic languages, distinguishes
|
||
* a dotted letter 'i' from a dotless letter 'ı' (U+0131 LATIN SMALL LETTER DOTLESS I).
|
||
* In these languages, each has an equivalent uppercase mapping:
|
||
* ı (U+0131 LATIN SMALL LETTER DOTLESS I) -> I (U+0049 LATIN CAPITAL LETTER I),
|
||
* i (U+0069 LATIN SMALL LETTER I) -> İ (U+0130 LATIN CAPITAL LETTER I WITH DOT ABOVE).
|
||
*
|
||
* Unicode CaseFolding.txt defines this case as type 'T', a special case for Turkic languages:
|
||
* tr and az. PHP 7.3 parser ignores this special cases. so we have to override the
|
||
* ucfirst and lcfirst methods.
|
||
*
|
||
* See https://en.wikipedia.org/wiki/Dotted_and_dotless_I and T30040
