1428407 - Search within page should be agnostic of Unicode normalization form

Status: RESOLVED DUPLICATE of bug 640856

(Core :: Find Backend, defect)

Description

[Sascha Brawer]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20180103231032

Steps to reproduce:

1. Open https://de.wikipedia.org/wiki/%C3%84 in Firefox 57.0.4 on macOS
2. Select “Find” command from “Edit” menu
3. Search for ä(U+0061 U+0308)



Actual results:

No matches found


Expected results:

Should find all occurences of Ä, irrespective of what Unicode normalization form is used in the web page and the search term. At least, Firefox should convert the search string to Unicode Normalization Form NFC. Works fine with Chrome and Safari.

Comment 1

[Sascha Brawer]

Note that in the above form, the ä has been normalized to NFC. To reliably copy a decomposed string into the clipboard, run this command on the macOS terminal:

$ python -c "print u'\\u0061\\u0308'.encode('utf-8')" | pbcopy

This is a duplicate of a very old bug, bug 640856, which is waiting for a volunteer to do the work on it!

Thanks for the bug report!
