[css-text] Spacing in Canadian French

[xfq]

In this level, if the element’s content language is French, narrow no-break space (U+202F) and no-break space (U+00A0) is inserted where required by French typographic guidelines.

Canadian French is not mentioned in the link and the rules are different for Canadian French. There’s no extra space before question marks, exclamation marks, and semicolons, for example. We should probably need to add spaces depending on the region.

@xfq These rules should probably be maintained in some registry that isn't the CSS spec. Does the i18nWG want to main them at W3C or should this be part of Unicode CLDR somehow?

The link in the current draft to the French typographic guidelines no longer works.

Perhaps we should link to https://www.w3.org/TR/dpub-latinreq/#language-specific-spacing-rules ?
