   (Note: The separator is actually a semi-colon ';'.)

How would you like to fix this situation? 🤔

The easiest fix is to remove the note.
For those using mtr in scripts in the csv mode, it would be annoying to change it to follow the documentation.

In many cases, other separators are useful. e.g. when I export a bill-of-materials for a PCB design it will list 100nF, 0805, "C1, C2, C3" But although spreadsheets know how to parse that, it is difficult for "awk". So using semicolons because data can include commas is useful. I don't think the data can include commas in mtr output, so using a semicolon is not very useful.

If you want to change the code anyway, I suggest you allow to set it using an option and make the default a comma.

I don't think the data can include commas in mtr output, …

Can such data display be adjusted according to decimal separator settings? 🤔
