Good. 
First input:

MariaDB [(none)]> 
  SELECT x, length(x) 
  FROM 
    JSON_TABLE('{}', '$' COLUMNS (x VARCHAR(10) PATH '$.x' DEFAULT 'abcdefg' ON EMPTY)) jt;
+------+-----------+
| x    | length(x) |
+------+-----------+
| abc  |         3 |
+------+-----------+
1 row in set (0.000 sec)


Using VARACHAR(12) produces "abcd", so it seems the truncation length is one
third of the N in VARCHAR(N).

Is this utf8 characters vs bytes error somewhere? Please fix.

 Sergei
