Hi,
This whole discussion about stripping characters is not relevant for interop.
You can make a recommendation, but its clear that nobody will feel bound to it, as it is
irrelevant for interop and this feature to work.
If the XEP makes a recommendation, it should have a sound rational. What would that be?
Why is it important to you what different communities, clients or bridged networks choose
as plaintext representation of a mention?
Regards
Philipp
