It looks like the string went through the conversion from CP1252 to UTF-8 twice when using F9.

I don't know where that would be happening though...

A potential work-around could be to convert all your .m files to UTF-8. That would also help with compatibility of your files with Octave on Linux or macOS, and with versions of Matlab that aren't older than approx. five years.

The execution of a piece of code by pressing F9 (run selection) in the editor does not produce the same result as running the whole script or typing the command the console.
This leads to wrong result.

This only occurs when encoding is not UTF-8 (I only tested with Windows-1252 encoding).

The code to be executed is :   s_xx='é';

Hereafter, the results for the 3 cases (xx = F9, console or script)
