When converting a numerical value to text with grouping enabled, the grouping character that is used is not properly localized on a Mac. By default, the grouping character that is used when in the en-US locale is the comma character (,). When the OS locale and language has been changed to de-DE (German-Germany), the separator should be a dot instead of a comma, but a comma is still displayed.
This only occurs on a Mac. The grouping separator changes as expected on Windows.
No. This same behavior occurred in 4.20.
The text displayed in the TextBlock still uses a comma character (,) as the grouping separator.
The text displayed in the TextBlock uses a dot character (.) as the grouping separator.
There's no existing public thread on this issue, so head over to AnswerHub just mention UE-71839 in the post.
