Saving text files to ensure characters are correctly rendered (German English)?

Question

I'm currently translating content for our new Website and receive the files from a colleague as Text files - effectively he sends me the source from the WordPress page with all the formatting tags - e.g.

etc. and also some plug-ins. I have created RegExes to handle the most common one - a concertina effect (used frequently in FAQs - when "open" it shows the the question and the answers, when "closed" it just shows the question. [foldout title="QUESTION HERE TO BE TRANSLATED" Level="3"] with a closing [/foldout] after the answer. The main problem is that the texts use umlauts and ß in the German original - and these don't render correctly in the file that I translate in Studio 2015 - e.g. an "ö" becomes "Ã¶" etc. I am presuming somewhere the character Encoding is not set. Where does it need to be changed?

Hi Michael, 
 Probably in the source file itself if there is no encoding set. But there are options in Studio. This article might help:

Thanks Paul, 
 You were indeed correct - the problem was solved in Notepad++ by setting the character encoding to UTF-8 (there is also a without BOM Option - but for the reasons explained in your multifarious post that didn't work. 
 Full speed ahead now!
