Captions
Strike a wrong guess, then write the real line in plain text. A whole caption of combining marks is hard to edit later. Hashtags stay un-struck so they remain tappable. If you strike a hashtag, it may cease to be a hashtag. Leave tags un-struck. Struck lyrics still copy. If you do not have the right to share the lyric, do not paste it, struck or not.
Discord
Prefer ~~Markdown~~ in servers. Use this generator when Markdown is unavailable (nicknames, other apps). Login names stay ASCII. Nickname strike is Unicode-only. Channel strike can be Markdown. Mixing both on the same nick does nothing useful.
Bios
A short struck joke under a plain name. Combining marks count toward 150 characters. If the bio looks like tofu, switch to a simpler strike. A struck joke in a bio still counts toward 150 characters including every overlay. Budget for marks. Hashtags that include a strike overlay often stop being tappable. Leave tags in A–Z and strike the sentence next to them. Each overlay still counts toward the bio character budget.
Lists and prices
Struck prices are a visual gag; they are not a commerce format. Do not rely on Unicode strike for legal disclaimers people must read. Fake “was $99 now $9” strike is a visual, not a store catalog. Don’t use Unicode strike as your only price record.
