Hi! This is also a problem in Welsh [0]. In the Fluent world we solve that on the level of design principles (do not reuse the string `yes` because it can be translated to a different `yes` in different buttons) and bindings (compound messages allow us to localize a whole widget with a main message and its yes/no options).

Doesn't Chinese have understandable localizations for affirmative/negative responses like "是" and "没有"? I don't see the problem.

That's roughly like putting [OK] and [Cancel] into a dialog box that asks "Do you want to save this document?". Perfectly understandable but awkward, somewhat confusing to non-tech people--in a word, unfluent. Answering such questions in Chinese (and I imagine, in Welsh) requires the verb that was used in the question.
