Is your feature request related to a problem? Please describe.
When using the data collected via the form elsewhere (e.g. in print or on a web page), space there might be limited. Therefore it could be helpful to set custom character limits for short answers, long texts and other fields.

Describe the solution you'd like
Add a Character limit checkbox to the ... options of the appropriate question types.
Ideally, there would also be an indication of this limit when filling the form i.e. 18/70 or 52 characters left maybe in the lower right corner of the field.

Describe alternatives you've considered
I guess, this could also be solved by allowing the form creator to enter a regex, against which the answer is checked. While more powerful, it would be harder to use and potentially very confusing for the form filler.

Start by locating the question-type option menus for short answers, long texts, and other fields, then find the corresponding answer-entry views. Review how question settings and responses are stored before deciding where the limit belongs. Done means creators can configure a character limit, answers respect it, and the form filler can see the current limit or remaining characters.
