JabRef's current encoding list lists possible encodings.

The strings have flaws:

• UTF8 and UTF-16 are possible encodings. I really dislike the inconsistency between them: UTF8 has no -, but UTF-16 has: Both should have a dash resulting in UTF-8. (see https://de.wikipedia.org/wiki/UTF-8)
• Cp1251 should be CP1251 (see http://man7.org/linux/man-pages/man7/cp1251.7.html for example). Similar for all other code pages
• ISO8859_15 should be ISO8859-15 (see https://de.wikipedia.org/wiki/ISO_8859-15). Similar for all other encodings

On the one hand, I am very well aware that a change here results in a large compatibility code where the old strings have to be mapped to the new strings. On the other hand, I would like to see JabRef having strings not causing confusion.
