While saving to a local .txt, [ and ] are saved as _

OK, i'm what you would call a Noob if it's about Bug reporting.

Windows 10, AlephNote 1.6.16, Active account is "Filesystem", UTF-8

I wrote myself some Notes to do after a new Windows 10, Linux and Android installation and those textfiles contain [ and ] in the title. It's fine if i don't do anything but if i edit a Note and save it via Synchronize, AlephNote changes [ and ] to _

For example:

[Windows 10][Registry] Ordner im Arbeitsplatz

is saved as

_Windows 10__Registry_ Ordner im Arbeitsplatz

Yes, I replace invalid characters in the note title with an underscore, because some characters are not allowed in filenames (e.g. \, /, :, ?, ....).

But I guess on windows square brackets are also valid filename characters, I will fix this in the next version

PS: I've edited your issue to show the underscores (just put them into code blocks by surrounding them with backticks)
