No warning or error for some illegal characters cross-platform

Steps to reproduce

In Linux:

  • Create note with quote in title: my “note”
  • Or, create folder with period at the end: U.

Expected result

I expect the resulting title or folder name to be considered illegal

Actual result

In Windows: Syncthing fails because Windows will not allow quotes in the file name, or a folder name ending with a period.

we used to forbid cross platform illegal characters and people complained because “I am on a Mac why should I be bound by windows file system limitations (and viceversa + mobile).”

So, now it’s on you to know your devices and their naming limitations.


why not make it an option in the files & links settings section. and while you are at it, add one option to replace spaces with dash or underscore
