Re: [csswg-drafts] Backslash & Yen sign behavior (#6848)

@duerst I can't speak for Microsoft's font teams on your proposed 'solution', but my guess is that it wouldn't fly with customers in Japan and so wouldn't be viable. 

The real issue is existing content that uses U+005C instead of U+00A5 (or U+20A9), or any implementations that might be generating new occurrences of U+005C as the currency sign. I'd suspect that current versions of the most commonly-used fonts (certainly, current versions shipped by Microsoft) do have U+00A5 (or U+20A9) mapped to an appropriate glyph. If input methods and currency formatting APIs were outputting U+00A5 (U+20A9) and not U+005C, then that would at least prevent new occurrences. Then the key problem for users becomes one of searching and editing: if a Japanese user searches for U+00A5, that should match occurrences of U+005C, or vice versa. (Similarly for Korean.)

Looking at the current Japanese IME in Windows, when set into Japanese mode, pressing the \ key presents three candidate characters, in this order: U+00A5, U+FFE5, and U+005C.

Using the soft keyboard for Japanese, though, I've only found ways of entering U+FFE5 or U+005C (according to the Japanese/Roman mode).
