Internal editor font bug (newly typed text is shown in different font)

For the last few versions of WinSCP on Windows 10 I have noticed that any text I type when editing a text file on the server is shown in the wrong font.
When I paste the text contents from the Editor to WordPad, it shows that the newly typed lines use Calibri instead of Consolas.
If I then save the text, close the editor and re-open it, everything will be shown with the correct (Consolas) font again.
I have attached a screenshot of the issue.

Details:
- Clean install (all settings reset) of WinSCP 5.17.8 (Build 10803)
- Problem started occuring sometime in the last year
- Windows 10 64-bit (currently version 2004, OS build 19041.572, but same bug occured on previous builds, too)
- SFTP-3
- Commander style GUI
- Steps to reproduce: edit any text file using the internal editor

Thanks for your report. Though I cannot reproduce the problem. What I did:
- start WinSCP 5.17.8 with the default settings: winscp.exe /ini=nul
- cancel the Login dialog
- open any local file in the Internal Editor
- type some new text into the file
- copy and paste to WordPad
- everything is in Consolas font (what is clear even in the Internal Editor)

Hello Martin,

thanks for your reply! The steps provided didn't help, but I managed to find the issue:
It's the language settings (English - Slovenia) of my system! (Screenshot attached). When I changed everything to English - United States, the font bug went away.

Thanks for sharing your solution.
