See https://www.sqlite.org/fts3.html#custom_application_defined_tokenizers https://www.sqlite.org/fts3.html#custom_application_defined_... Since 2016, arguments to the fts3_tokenizer() function must be variables (ex: ? or :var or @var or $var) to which values are supplied by the application at run-time using sqlite3_bind_pointer(). There is no way to do this from pure SQL script. Nor is there any way to do this from within a view or trigger. There is no way to invoke fts3_tokenizer() from a maliciously corrupted schema or database.
