Cloze Questions offer wrong spellings as correct answers.

[ISN-Zurich]

A wrong spelling should be a partial correct answer and not be suggested as a correct answer.

Expected behavior:

if the input does not match any correct answer, the answer should be tested as follows:

1. Lowercase both the provided and the correct answer.
2. remove all duplicate letters from the correct answer and the provided answer.
3. replace all accent characters (e.g. é, ç) with their non-accented counter part for the correct and the provided answer.

If the provided answer now matches any correct answer the feedback should be partially correct.
