7 Discussion

Killing, Alexander [alex], 15.11.2016: I support this request.

JourFixe, ILIAS [jourfixe], Nov 21, 2016: We appreciate this suggestion and schedule the feature for 5.3. The counting of characters (and the warning if too many are used) should be done during runtime and not after saving the input. This should be done on client-side (ignoring HTML characters from the Tiny). As already decided for Mantis #18956, this function

• (a) should give clear information how many characters left or how many characters are too much (instead of "-11 characters").
• (b) should try to avoid counting embedded HTML strings.
• We recommed to re-use the revised input for Essay questions in T&A (and Survey as well).
