Dear Philippe,

I can confirm the issue with your data file but I still think that this
file was written with a different char code convention.

Here is a minimal example that works with both definitions:

str = "µ";
//str = fromCharCode(956);
xstr = "x [" + str + "m]";
setResult( xstr, 0, 123 );
updateResults();
//
xval = getResult( xstr , 0 );
print( xval );
str = String.getResultsHeadings;
print( str );

Best

Herbie
