User stories for numbering system #14
Description
In recent discussions, it's been suggested that the numbering system setting is qualitatively different from some of the other settings, but realistic user stories haven't been documented so that participants who don't have first-hand experience with using non-ASCII digits could understand the issue.
It would be helpful to document realistic user stories.
In particular, Windows has a setting "Use native digits" with three options "Context", "Never", and "National". I don't know how this works, but I infer these to mean:
- Use the digits associated with the surrounding language.
- Always use ASCII digits.
- Always use digits specified in the "Standard digits" preference.
For fingerprinting quantization, it would be useful to know if the third option is there just "for completeness" or if it is associated with a realistic user story. That is, do users want use non-ASCII digits with English, or is the pref really a boolean: Match surrounding text vs. force ASCII digits regardless of context? (With the setting being moot for languages whose associated digits are the ASCII digits.)
Also, it looks a lot like, in contrast to temperature units in particular, the numbering system setting with values other than "latn" (in the sense of forcing ASCII digits in all contexts) isn't a standalone setting. (See #13)
