getFirstLetter()

MediaWiki\Collation\IcuCollation::getFirstLetter

(

$string

)

Given a string, return the logical "first letter" to be used for grouping on category pages and so on.This has to be coordinated carefully with convertToSortkey(), or else the sorted list might jump back and forth between the same "initial letters" or other pathological behavior. For instance, if you just return the first character, but "a" sorts the same as "A" based on getSortKey(), then you might get a list like== A ==

• [[Aardvark]]

== a ==

• [[antelope]]

== A ==

• [[Ape]]

etc., assuming for the sake of argument that $wgCapitalLinks is false.

Since

1.16.3

Parameters

Returns

string UTF-8 string corresponding to the first letter of input
