Request for additional named entities for invisible/ambiguous characters #1841

r12a · 2024-03-28T12:05:12Z

Instructions:

This follows the process at https://w3c.github.io/i18n-activity/guidelines/review-instructions.html

Create the review comment you want to propose by replacing the prompts above these instructions, but LEAVE ALL THE INSTRUCTIONS INTACT
Add one or more t:... labels. These should use ids from specdev establish a link to that doc.
Set a label to identify the spec: this starts with s: followed by the spec's short name. If you are unable to do that, ask a W3C staff contact to help.
Ask the i18n WG to review your comment.
After discussion with the i18n WG, raise an issue in the repository of the WG that owns the spec. Use the text above these instructions as the starting point for that comment, but add any suggestions that arose from the i18n WG. In the other WG's repo, add an 'i18n-needs-resolution' label to the new issue. If you think any of the participants in layout requirements task force groups would be interested in following the discussion, add also the appropriate i18n-*lreq label(s).
Delete the text below that says 'url_for_the_issue_raised', then add in its place the URL for the issue you raised in the other WG's repository. Do NOT remove the initial '§ '. Do NOT use [...](...) notation – you need to delete the placeholder, then paste the URL.
Remove the 'pending' label, and add a 'needs-resolution' tag to this tracker issue.
If you added an *lreq label, add the label 'spec-type-issue', add the corresponding language label, and a label to indicate the relevant typographic feature(s), eg. 'i:line_breaking'. The latter represent categories related to the Language Enablement Index, and all start with i:.
