v1.21.2
Forum tags are matched per word
A tag named ℹ️ Info did not match Info, so it was never applied. ℹ is U+2139 INFORMATION SOURCE, which Unicode classifies as a lowercase letter, so stripping non-letters left it attached to the word. The variation selector that marks emoji presentation would distinguish it, but Discord removes that when storing a tag name.
Tag names are now read one word at a time. An emoji, a grouping label or a priority prefix is a separate word, so P1 Critical matches as well. Only whole words match, so Informational matches nothing.
Info severity uses 📘
Cards, the route editor and the docs use 📘 for info severity instead of ℹ️, so a tag named after the card's emoji works.
No re-connection is needed. Matching runs against the tag list already stored for the channel.
