I have seen several cases recently when Matching questions are very sensitive to any kind of special characters. So I was wondering if this is a bug or if we have a workaround.

Answer1:   Reasonable Domain   Match1:    0<x<9
Answer2:   Reasonable Range     Match2:     0<x<250

If you type exactly like this, then you will see only the first character (0) in the drop-downs

matching

If you will type 0 < x < 9 (add spaces), then you will always get it "wrong", unless you remove < characters.

matching2

I confirmed this on several M2 instances, including demo site.

 

Other characters that I had sometimes to remove from matching questions were '  "  and ...

@Elena,

But it still does not work smutny

I do add spaces - then I attempt the question, answering it correctly. And then my answers are always "incorrect" ... (see my second screenshot).

You're right, this is definitely a bug. One workaround is to invert your left and right columns, i.e. place the "formulas" containing < or > signs in the Question field and the "normal text" in the Answer field.

Answer1: 0<x<9      Match1:    Reasonable Domain  
Answer2: 0<x<250  Match2:     Reasonable Range

Reported as MDL-35448. Interested people please vote for it!

@Elena, if you can hack your moodle core files, you can use the patch I provide in the tracker, it's only 2 lines to change.

Quotes and Spanish characters work OK for me.

If you want to provide more examples, please give the text of matching pairs as text, not as a screenshot image, so I can simply copy-paste.

I guess if I will copy/paste the ones from my example above - it would not help to replicate the issue. But just in case: 

1. First choice

1. First match

2. Second choice

2. Second match

3. Third Choice

3."Third match"
