note 59004 added to function.recode-string

Here's how to convert romaji to katakana/hiragana with PHP (transliterating Japanese text). The function Romaji2Kana($s) will return with keys 'hira' and 'kata' that respectively contain the hiragana and katakana versions of the given string in UTF-8 encoding. <?php // eucjp: 2421; unicode: 3041 define('HIRATABLE', 'a A i I u U e E o O KAGAKIGIKUGUKEGEKOGOSAZASIZISUZUSEZESOZO'.

It supposed to contain aiueo with circumflex and aiueo with macron. - The strings in the defines should be constant, not appendage expressions.
