[Solved] Prevent two hyphens in a string from being treated as a comment

Hello
I have the following SQL

SELECT
CASE
WHEN bs = 'B
THEN '12Xkljsdg--X'
ELSE receiverid
END AS buyerparty
from base.

However, if I have selected the setting that "Convert Line comments into Block Comments", it destroys the SQL for me.
The result is then:

SELECT
CASE
WHEN bs = 'B
THEN '12Xkljsdg/*--X'*/
ELSE receiverid
END AS buyerparty
from base

which is wrong.

How can I prevent this?

Greetings
Ben
