XML .dim file encoding

Is there any reason that the .dim xml files are encoded in “ISO-8859-1” and not “UTF-8”. This causes problems when processing data with file names that contain non-ascii characters.



<?xml version="1.0" encoding="ISO-8859-1"?>

When I open .dim files with visual studio code (which auto detects the encoding), it says that the file actually is encoded in UTF-8. Seems that there is a mistake somewhere in the software, and it is setting the encoding attribute wrong in the beginning of the XML document.

The encoding is set to ISO-8859-1 since 20 years, or so. Since the format was implemented.
A recent try to set the encoding to UTF-8 lead to some issues.

This is just one of the reasons why we are working on a new format.
