Files with invalid characters like * do not get synced on Android

[Pch]

I don’t think this is a bug … In the sense that * appears to be one of the forbidden characters on Android (for, apparently, “compatibility with Windows” reasons, after a very quick google search).

MacOS and iOS are way more tolerant than Windows when it comes to forbidden characters… Hence why the files can be synced to those devices but not Android.

This post could be relevant :

Files with question marks (?) on name title aren't being synced on mobile

And unfact we do! We used to restrict to a common character set. But a sizable fraction of users complained because while using a mac they didn’t want to be restricted by illegal characters on windows. So now the character set is unrestricted and you are responsible for defining a filename that is compliant. The long term solution this problem is likely this: https://forum.obsidian.md/t/use-h1-or-front-matter-title-instead-of-or-in-addition-to-filename-as-display-name/687

And this FR, potentially too …

Support any character in filenames / note title (using encoding, substitution, etc)

Some characters aren’t supported in file names (e.g. “:”), hence in note titles. The proposal is to support them by using percent encoding. Use case or problem I’d really like to use characters such as “:” in note titles but I can’t. Proposed solution Support any character in file names by using percent encoding for commonly unsupported characters (“:”, “/”, "", “?”, “%”…). Platform specific character constraints on filename wouldn’t leak as constraints on note titles It would be transparent…
