obsolete wiki template producing just one char "|" AKA wall, not needed anymore since this is a parser function now (since year 2014)
Magic word documentation view] [edit] [history] [purge]
The magic word {{!}} is used to escape a vertical bar character "|" in wikitext markup, causing the parser to temporarily not interpret it as a special character.
Discovered by embedding cosine similarity (sentence-transformers MiniLM, 384-dim).
