1. 8 core/lib/Drupal/Component/Transliteration/PhpTransliteration.php \Drupal\Component\Transliteration\PhpTransliteration::readGenericData()

Reads in generic transliteration data for a bank of characters.

The data is read in from a file named "x$bank.php" (with $bank in hexadecimal notation) in PhpTransliteration::$dataDirectory. These files should set up a variable $bank containing an array whose numerical indices are the remaining two bytes of the character code, and whose values are the transliterations of these characters into US-ASCII. Note that the maximum Unicode character that can be encoded in this way is 4 bytes.

Parameters

$bank: First two bytes of the Unicode character, or 0 for the ASCII range.
