They mention it's a custom version of base83: https://github.com/woltapp/blurhash/blob/master/Algorithm.md...

With this charset: 0123456789ABCDEFGHIJKLMNOPQ RSTUVWXYZabcdefghijklmnopqr stuvwxyz#$%*+,-.:;=@[]^_{|}~.

I imagine you could tweak that to replace problematic chars with safe substitutes.

These are the safest I could find. They are perfectly fine for using in filenames.

Windows "A file name can't contain any of the following characters":

    \ / : * ? " < > |
which means "*:|" would need to be removed if you want to support that use case

That depends very much on the platform ...

Well, Windows is very picky, yes.
