Strange fonts in my filenames

[dimzev]

In the photo you will see that in some spreadsheet files that I downloaded from a public service their names are not read.
The content is read normally.
The names are probably in Greek Font

What must i do ?

@dimzev, To facilitate help, paste two or three file names into your question.

The names probably were in Greek.

By the way, not a Calc question.

please see above…
Please give me what tags must add

This could help if you could give an expected filename. E.g. 2éä 2019 ÅÉÄæùÉêîÇ may contain a month or abbreviation for a month. With this, we could try to guess which sequence of processing occurred to mangle the names. I guess the name was initially UTF-8. You say you downloaded it from internet, probably from an ISO-8859-x which took the names without translating them and then it landed on your UTF-8 computer again without conversion (or converting supposed ISO-8859-x into UTF-8 sequence), leading to this mess.

And Google Drive does not help at all because I can’t access the raw names! Everything goes through scripts which add their own mangling.

@dimzev, use only tag file-name, and in the question may be strange filenames. Thanks

The filenames are obviously in a different encoding than what you have for your system.

The plan -

1. Find out the correct encoding of your filenames

2. Convert the file names into correct encoding

3. Encoding here means the way how the font is typed and the font itself. Click one time on a file name as if you rename it, select it all, and then copy-paste in Universal online Cyrillic decoder - recover your texts . Try the “select encoding” or select a successful sample, or Expert, all of the three until you find the right encoding. I tried it with yours but wasn’t successful.

4. When (and if) you have found out the correct encoding you have to rename your files. My favorite software for this is Total Commander. If you install Total Commander, navigate to the folder with your files and select them all. Then press Ctrl-M. In the “Multi-Rename Tool” window which appears press on the little folder icon in the section Upper/lowercase. Select “Edit names…” and Notepad will appear with the file names in form of a simple document, each file name one line in the text. You can rename them or if there is a mass decoding software for your encoding simply convert the text and replace the original in the renaming document. Close the document, press OK in the accompanying window of confirmation, and finally, Start! button to rename your files.

Hope this helps.
