@yesfreenet Yep, something wasn't right during the sending of the text from one platform to another (or probably one instance to another). At least what can be deduced since the HTML only appeared in: mastodon.ml/@yesfreenet/110153

Maybe there was a function that is not compatible. Or, the transmission of the data was corrupted or malformed. Or, something was a misss in the mastodon.ml instance database, it wasn't able to interpret data from quietplace.xyz instance.

Probably encoding incompatibility? At least that's the only one I used to encounter before UTF-8 became common.
