Description

This is a follow-on to cldrbug 6856: about the following:
In most cases, if we take one of the standard date formats for a locale, treat it as a skeleton and get the corresponding pattern from the availableFormats, we should get back the original format. There are some exceptions:

  • When the format includes 月 or 월 (or 'tháng' for Vietnamese) such as y年M月d日, the derived skeleton does not really represent the intent of the format.
  • When the short and medium formats are both numeric but not the same, a roundtrip through the availableFormats may not match one of them.

We have an existing warning that attempts to address this; we may need to refine it and turn it into an error in some cases (See discussion in cldrbug 6856:). We also need to fix the remaining real roundtrip problems that were not addressed by cldrbug 6856:
