A user is reporting to me that he gets an InvalidFormatException. The stack trace looks like this:

which tells me it’s in my imageWrite method. Further, there’s only one “new FolderItem” in the method, which looks like this:
Var s as String, f as FolderItem
s = "/path/to/some/myfile"
f = new FolderItem (s, FolderItem.PathModes.Native)
So I’m concluding that some part of s must contain invalid characters, an idea which is supported by the doc for InvalidFormatException. But what characters are invalid? I’ve tested with a non-existent path, but the FolderItem is created OK, so it can’t be that (what happens with a non-existent path is an IOException if I try to create the file).
It’s not slash (/) or colon (:), as I already filter those out. So what characters can generate an InvalidFormatException? StackExchange doesn’t appear to think any character is invalid.
