Hi Andreas,
I'm saving the value of one single java.lang.String instance to a file.
Right now, the generated file uses a UTF-16 encoding, for which support
in 'common' programs/tools is kind of spotty.
I'd like to have at ASCII or UTF-8 as options:
1) UTF-8 is pretty well-supported in most editors/tools
2) ASCII is universally supported of course
In the case of ASCII, it's possible that the String instance contains
non-ASCII characters. If this is the case, I'd like MAT to notify me,
and abort.
So, in summary, my use case applies to strings only, and the main
motivator is the relatively spotty support for UTF-16.
-tt
P.S. Any chance for a new release sometime soon? :-)
