[issue19819] reversing a Unicode ligature doesn't work

[Christian Heimes]

Christian Heimes added the comment:

A proper str.reverse function must deal with more extra cases. For example there are special rules for the Old German long s (ſ) and the round s (s). A round s may only occur at the end of a syllable. Hebrew has a special variant of several characters if the character is placed at the end of a word (HEBREW LETTER PE / HEBREW LETTER FINAL PE).

A simple reversed(s) can never deal with all the complicated rules.
