602459 - Ignore embedded whitespace between first-letter and punctuation

Status: NEW

(Core :: Layout: Text and Fonts, defect)

Description

[Simon Montagu :smontagu]

In bug 399941, I chose to take whitespace into account when determining whether there was punctuation preceding or following a first-letter.

This was probably the wrong decision: as pointed out in http://lists.w3.org/Archives/Public/www-style/2010Oct/0030.html, French typographical practice always puts a space between text and double angle quotation marks (guillemets).

Attachment: Testcase

The testcase uses ASCII space, non-breaking space, and thin space (U+2009) between the text and the guillemets.

Would this mean allowing line breaks inside the ::first-letter?  That seems dangerous.  (I'd also like to move first-letter handling to frame construction.)

I agree about line breaks, and the same goes for tab characters.

In Norwegian there is also whitespace between the punctuation and the first letter:

Example:
– Pettersen, ropte hun, – kom inn og få kaffe.

The spec should be updated to support non English languages.

The CSS Working Group have discussed the issue and concluded:

Waiting for the editor's draft to be updated.

Comment 7

[Johannes Odland]

The editors draft has now been updated:

Punctuation (i.e, characters that belong to the Punctuation (P*) Unicode general category [UAX44]) that precedes or follows the first typographic letter unit and any intervening space separators (characters that belong to the Zs Unicode general category [UAX44]) must also be included in the ::first-letter pseudo-element.
