Tag value warnings about rosemary HOT 6 OPEN

Forgot to add screen dump:

from rosemary.

This error message does not make any sense to me. Is it because of multiple whitespaces in the description text? Or is there a special character in it?

from rosemary.

Both, see hex-dump.

from rosemary.

Ok, thanks for providing that. Even then I'm not sure if it wasn't job of the API to make sure clients don't send "malicious" data and refuse to serve these API calls.

It's easy to implement a check for double whitespaces. But hey, i can see people with pitchforks and torches coming after me because there is a very good reason to support double whitespaces as tag values.

What is the statement of the OSM API maintainers?

Maybe a warning can do it.
Like JOSM editor do.

Rosemary editor

According to https://github.com/sozialhelden/rosemary Rosemary is API client, not editor. Creating a proper editor requires (among others) handling poor/invalid user input.

It looks like the Rosemary editor can create a tag that gives warnings in JOSM editor version 11441.

It did what user instructed it to do, right? It is not a job of API client to run validation rules like that - it should be implemented in editor itself.
