(ok 2.11.2) Character \'+\' in query wrongly interpreted

In v2.11.0 when the SQL SELECT query contains the plus ('+') character, after results are shown, if the [Show] button is used then the plus character is translated into a space (like in URL encoding).

To test:
SELECT * FROM my_table WHERE my_column LIKE '%+%'

Test the above on a table which can be like
CREATE TABLE my_table (my_column VARCHAR(32));
INSERT INTO my_table (my_column) VALUES ('+1'), ('+2'), ('+3');
