This issue is applicable to Chinese and Japanese.

In Japanese composition, it is usually recommended to apply extra spacing between Japanese and Western text to increase the recognition of Western text.

Currently, browsers do not support this feature, so content authors have to work around the problem by adding spaces manually.

For more details, see this GitHub issue, which is being used to track this gap. Please discuss this issue there.

There exists a css-property to deal with that in css-text-4: https://drafts.csswg.org/css-text-4/#text-spacing-property

text-spacing: ideograph-alpha ideograph-numeric

I don't believe it to be implemented anywhere yet, though.

@frivoal Yeah, I also mentioned it in w3c/clreq#401 (although I didn't mention ideograph-numeric). I think the current CSS spec has at least two potential issues:

Hmm. This discussion would be better held at w3c/clreq#401, since it is the issue which is being tracked by the gap pipeline. Implementers using the pipeline may not see this thread.

(Perhaps the boilerplate text should indicate where to hold discussions.)

FYI,

There exists a css-property to deal with that in css-text-4: https://drafts.csswg.org/css-text-4/#text-spacing-property

text-spacing: ideograph-alpha ideograph-numeric

I don't believe it to be implemented anywhere yet, though.

text-spacing: ideograph-alpha ideograph-numeric is being implemented in Vivliostyle very recently.
