[MonoDevelop] Source encoding

[kent sin]

How to specify the encoding of source files?

I try to open some code in MonoDevelop, it got the encoding wrong. I
am thinking to convert the encoding, but that would make it difficult
for the original coder.

What is more problematic is that if I did not findout the current
encoding is wrong, and I put some thing in with a different encoding,
after some more code exchange with the other party, that code will
have a mixed encoding.

Is it possible for MonoDevelop to recognize like python some form of
encoding hint in the comment at the start of a source file?
