Re: [csswg-drafts] Support for double hyphenation across line breaks (typographic convention) (#13688)

Thanks, this clarification is very helpful — you're absolutely right that my original description was too broad.

What I had in mind is specifically the case where a line break occurs at an existing (explicit) hyphen, such as in compound words (e.g. "Grot-Rowecki"). In this situation, some typographic conventions repeat the hyphen at the start of the next line to make it clear that the hyphen is part of the word rather than introduced by line-breaking:

Grot-
-Rowecki

As you point out, this is distinct from automatic hyphenation (e.g. syllable-based breaks), where such repetition is not used.

I also agree that this behavior is context-dependent (e.g. dictionaries vs. general prose), and not purely language-driven, which suggests that it should be author-controllable rather than implied solely by lang.

So perhaps the core gap is:

CSS currently does not provide a way to control how explicit hyphens at line breaks are rendered across the fragmentation boundary.

In particular, there is no way to indicate whether an explicit hyphen should be visually repeated at the start of the next line.

A property in this space (e.g. something like hyphen-repeat: auto | none) could allow authors to opt into this behavior where appropriate.
