I restored UltraCompare version 18.00.0.45 from my archives and compared the two text files with that version. Now I could see the grave accent in both file panes above fourth character б instead of third character ё respectively e. That was important to know for me. I updated UC next from my archives to version 18.00.0.47 and the display issue remained. I updated once more to version 18.00.0.62 and the text display became correct. UltraCompare 18.00.0.80 and 18.00.0.86 showed the text also correct in both file panes using Consolas version 7.00 on Windows 7.
I looked in my archive of hotfix information published by UltraEdit, Inc. for all UltraCompare 18.00 versions and could not see an explicit note about a fix of this text display issue. But the published hotfix information contained also several other minor issues addressed and this display issue is definitely a minor issue for a comparison tool. However, the wrong display of the text is definitely fixed in currently latest UltraCompare and definitely also in several former versions.
It is impossible for me to find out on which version is based on the non-public published version 2022.20.0.42. You could send an email to support of UltraEdit, Inc. and ask for EXE installer or MSI file depending on current version installed with EXE installer or MSI file for UltraCompare 2022.20.0.45 in language X If the purchased license is for UltraCompare 2022.20 to have finally installed a public version of UltraCompare with a fix of this text display issue on using Consolas.
