I just discovered the “synonyms” feature at the bottom of the info page for a tag, specifically the “c#” tag.
For a laugh, and just to try the feature, I entered “c♯”. This is the Unicode Character “MUSIC SHARP SIGN” (U+266F). Now I recognise that StackOverflow might not want to complicate everything by allowing such outlandish characters, but the point of my report here is that the user experience was very bad:
- The system silently changed c♯ into just c and went ahead adding the suggestion. It should instead display an error.
- It doesn’t let me downvote or retract the suggestion (which of course wasn’t meant to be just c). It should let me remove it in case of mistake.
