function 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.

    $file = $this->dataDirectory . '/x' . sprintf('%02x', $bank) . '.php';
    // Read in this file, which should set up a variable called $base, which
    // will be local to this function.
    if (is_file($file)) {
        include $file;
    }
    if (!isset($base) || !is_array($base)) {
        $base = [];
    }
    // Save this data.
    $this->genericMap[$bank] = $base;
