Translation of comments containing umlauts

[ceeac]

This patch translates comments containing umlauts and other non-UTF-8 characters. This leaves only a handful of non-UTF-8 characters in the code (names and BOMs).

This patch translates comments containing umlauts and other non-UTF-8 characters.

UTF-8 does support umlauts. If it did not, it would not be Unicode compliant. If Unicode did not, then it would have failed one of its core design goals.

BOM on the other hand, does not belong in UTF-8. Unfortunately, some programs don't understand UTF-8 without it, and some don't understand anything with it.
