Hi Neesn, thank you for your detailed report.
Can you confirm the status of the (slightly hidden) Disable Regex box.
See https://docs.moodle.org/401/en/Gapfill_question_type#Disable_Regex
I just got this to work

It is not disabled

[marcusgreen]

It needs to be disabled (checked) if you don't want the characters to be interpreted as regular expressions. I think it could be clearer.

Super that seems to be working :-)
But you are right - a better description would be nice. Most teachers dont know what regex is.

[marcusgreen]

You are right, very few people will know will know what regex is. It can be disabled at a system wide level (I know if you are a teacher that may mean nothing). I was thinking some more about that today. A few years ago I changed it so that by default regex is disabled, but it would be good if whenever it is on a clear sign is displayed on the question editing page saying something like "Regex processing is enabled, characters like ?* etc will have a special meaning, do you want that".

Can I mention you in the update document if/when I update that, as I like to credit anyone who has given me feedback on how it works. Is there a longer version of your name, or shall I put neesn?
