It's VARBINARY in both my local database and on the live system (we can see it truncates at 255 bytes). I don't know how this happened. I assume the meaning of VARCHAR BINARY changed. It appears this was an alias for VARBINARY in the MySQL versions we use.
Here is an example search: https://www.wikidata.org/w/api.php?action="">. Note that the search result ends with \ufffd. This should be stripped, as @daniel suggests.
During story time we found that:
- Certain closed subtasks of T75087: Efficient entity label lookup (tracking) are probably the reason for this bug.
- The remaining open subtasks of T75087 will solve this specific bug.
- A much wider parent task T86530: Replace wb_terms table with more specialized mechanisms for terms (tracking) also exists, outlining a series of individual replacements necessary to get rid of the terms table.
We said that we will, for now, solve this bug by implementing the "fallback" workaround described in T142691#2543325.
