Htmlform-no and Htmlform-yes
Indeed; as Nike said:
Not really fan of this.
In Finnish:
Is the sky blue? Kyllä/Ei
Are you over 18 years old? Kyllä/En
There doesn't seem to be such thing as generic yes-no question.
We have some such samples in Rhinelandic and Ripuarian languages, too: Negative expressions or denying formulation of a question => Answer "no" signals consent. Two question and answers having identical meanings, translated literally:
- Q: Are you surely in good health? A: Yes, I am healthy.
- Q: You are not in a bad health condition, are you? A: No. I am healthy.
Not a real problem though, I think, since we can always make sure to use positive (denial-free) formulated questions, or unambiguous imperatives directed towards the computer, e.g. "Do include thumbnails: Yes/No"
I am not certain about the fine grain, but also many Slavic languages as far as I know "suffer" from uncertainties arising from formulations with negations in questions.
