[Idle-dev] Bug report for idle : problems with file save and unicode

[Cadet Alain]

On windows NT4 with a French installation (cp850), I get sometimes some
problems when I try to save a file.
I get an error and after :
1) it is impossible to save the file
2) the previous file is lost (file with 0K and nothing inside)
I got this several times. I notice nothing special except that the files
have special characters in strng values (ascii >128).

Here is the error message :
