[OSM-dev] How to write UTF-8?

[Maarten Deen]

I noticed some errors in the rails translation for the Netherlands (no UTF-8 
used) and I'm now a little stumped how to get the UTF-8 translation of characters.
Apparently ö (latin small letter o with diaeresis) becomes ö, but I can not 
find a translation table the tells me that.
I do find a table that says that it is hex C3 B6, but if I enter that (windows 
trick: type it in dec with alt-numpad) gives me different characters.

Can anyone suggest either a website that does this translation for me or an 
editor for Windows?

Maarten
