This optional string value allows you to override the standard sort order of System.Title. In Chinese, Japanese, Korean locales (like CHS Pinyin, JPN Hiragana, or KOR Hangul) it is important to set this string to the phonetic version of the title defined in System.Title. The first character of this string is also used for grouping files by the first letter of their title. For most non-CJK languages, this field does not need to be set (in which case System.Title will be used), but you can use this property to override the sort order or grouping letter (for example, to remove leading articles like "a" and "the") by setting it to the string that you prefer.
