WERFBLAU  True — it is a great app. Thanks to the developer.

@JO SPOCK: I believe the problem with special characters like umlauts is at your end - I imported the parsed text-file into an OpenOffice spread sheet using Unicode (UTF-8) as encoding scheme - and had no problem with 'ä' etc. — everything is just fine. I checked the exported text file with a text editor (TextEdit doesn‘t get the correct encoding, too) — smart editors like BBEdit get all special characters without any problem.
