Hi TempodiBasic,
I tried to create a folder using unicode characters in the name. This folder will show up in the folder list, but it has a distorted name. Unicode characters are written nonsensically (I have the default IDE setting). When you open this folder, no files in this folder are displayed, even though the folder contains them. This is likely due to a badly translated folder name followed by an invalid path and therefore an empty folder will be displayed. IDE 1.3 behaves the same way.
This is the reason in the past why I dealt with short and long file and folder names. Libraries from Eoredson provide a solution to this problem under Windows. I don't know how to deal with it in other systems. The libraries, including the programs (and the program I used to do it for), are here somewhere on the forum.
You can set the font in the DISPLAY item, but this has no effect on file and folder names, they are still displayed poorly, although the unicode text after this change is fine in the IDE after writing this.
Here I noticed the fix, IDE 1.4 already correctly centered queries to save the program when the font is used. This is a very pleasant change.
