As I have repeatedly mentioned on this mailing list, I use a simple text editor. 
Please note that it does not matter what tool someone uses to modify a file as 
long as its format is preserved.

This is because of the default properties file format (see JDK API documentation 
on java.util.Properties) encoding non-ISO-8859-1 (Latin-1) characters as UCS-2 
characters with \uXXXX escape sequences. Although umlauts are part of the 
ISO-8859-1 character set their code points lie beyond the US-ASCII character 
set's code points. Tools like OpenJDK's native2ascii for converting files to and 
from different encodings are rather conservative in handling non-US-ASCII 
encoded files. Anything beyond the US-ASCII character set code points gets escaped.
If you wish to read the message property files in their non-escaped form, you 
can use native2ascii to convert them to any character set encoding that includes 
code points for their respective escapes. UTF-8, ISO-8859-1, ISO-8859-15, 
windows-1252, or x-MacRoman should the job for you. There are even others but 
they should not confuse you.
