Linking another conversation: Issue opening files from Google Drive Fin… - Apple Community
Confirming that this is happening on files coming from other locations, such as Google Drive.
It seems it is happening on files (most probably not only) with UTF-8 encoded diacritics. Example in Czech language: řžýá.docx will result in files not opening, rzya.docx will open fine
Affecting not only Google Drive app but also download - note below, depending on browser.
Reproduction steps for Google Drive:
1) Create a document in Google Drive (web)
2) Name it with diacritics / non-ascii chars
3) Download it as DOCX
4) Try to open the document - Word will launch but will fail to open the file without any error.
5) After the document is renamed (anyhow), open will work just fine.
At the moment, we think this is not a specific Google Drive issue (the same happening at other similar apps we tested, including one we developed).
Also, it's interesting that Safari is not affected (or so it seems). It looks like Safari is doing something that is converting the filename on download.
Example:
Character "í":
1) stored as c3ad in UTF8. This will be how Chrome downloads it if you type this char into document name e.g. in Google Drive and download as DOCX.
2) macOS Ventura 13.3 stores it as 69cc81 (in fact i + ´). This works fine.
