special characters in tags

[Maarten Deen]

The API documentation should describe the allowed characters to use, and it does: https://wiki.openstreetmap.org/wiki/API_v0.6#Tags
"A tag is a Key-Value pair of Unicode strings of up to 255 full unicode characters (not bytes) each."

No exemption of characters is made so that would imply that a "+" is allowed.
Having the JOSM validator flag them could be problematic in a way that people could take that as the rule and start removing all those characters just because JOSM says so.

Maarten
