Strange Number Format

[Claus Dietrich <claus.dietrich@xxxxxxxxxx>]

Question: Why does

  System.Language = "de_CH.utf8"
  Print Format(1234567.89, "$,##0.00")

deliver 1_234_567.89 ?

It happens with the master as well with 3.22.0 on Linux Mint 22.0 
Cinnamon. The Swiss language package is fully installed.

The cli command

  LC_NUMERIC=de_CH.UTF-8 printf "%'.2f\n" 1234567.89

correctly delivers 1’234’567.89

Is this a bug ?

A good weekend to all and

best regards

Claus
