1- Create a question of the shortanswer type.
a) question text: If a=2 and b=5, then write the inequality equation between a and b.
b) correct answer: a<b

2- Test question and enter expected correct answer: "a<b"
a) you get the message that your answer is correct
b) the text of the correct answer is displayed as: "Correct answer: a" rather than the expected " Correct answer: a<b".

Diagnostic: the smaller than character < is interpreted as an HTML opening tag character.
Severity: This is not too bad since the student's answer IS marked as correct, but the truncated feedback message is of course misleading.
I expect this occurence might be fairly rare (Maths or science teachers using < > characters in their shortanswer questions).
Remedy: Maybe there ought to exist in a Moodle library a function which would scan text for occurrences of < > characters and decide whether they are genuine HTML tag markers OR just greater than and lesser than characters ?
