[Therion] Compiling error due to encoding

[Torsten Schnitter]

Hi all

Problem found and solved.

I do use commands to import different layouts inside the thconfig file:
   input ..\_Therion\_Layouts\area_blocks_hdens.th

This file was edited with XTherion and saved as "iso8859-1":

As someone can see: text de .... seems to be OK (especially the 
character ö)

When opening this file with Visual Studio Code it looks like:

Now the character does NOT look ok (and format of file is UTF-8 as you 
can see at the bottom of the screenshot)

Just changing within Visual Studio Code this single character in line 2 
(not changing the format) and saving the file does solve the problem:

But now the file looks somehow wrong inside XTherion:

Seems to be a problem with XTherin file editor and file formats....
Attached the actual and working layout file.

For me I will not use XTherion file editor anymore and will edit files 
with Visual Studio Code.

best regards, Torsten
