256265 - Search/Quick search/Filters do not ignore case for accented letters (non A-Z)

Status: RESOLVED DUPLICATE of bug 254740

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Magnus Ihse Bursie]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7) Gecko/20040626 Firefox/0.8

When you type "foo" in the quick search box (or whatever it is called, the one
that filters down the displayed mails), it matches a subject/sender named "Foo"
or "fOO" as well.

However, this case insensitive search is NOT performed for international
characters, such as the letters "åäö" used in Swedish. If I search for "föö" it
does not match "FÖÖ".

This is unexpected and annoying for a Swedish user. Bad handling of non-A-Z
letters used to be a thing of the past.

Reproducible: Always
Steps to Reproduce:
1. Send yourself a mail with subject "FÖÖ"
2. Type "föö" in the quick search box.

Actual Results:  
No mails will be displayed.


Expected Results:  
Displayed the one you sent in step 1.

I'm using Thunderbird version 0.7+ (20040813).

This is a core MailNews bug.

quick search part depends on bug 254740. search (and probably filtering) on
local folders (and perhaps on Pop3 folders) also depends on bug 254740.
Search/filtering on Imap folder seems to be a different issue.

Btw, with my trunk build on Mac OS X, even case-sensitive search doesn't work on
a n imap folder for non-ASCII characters. 1.8a6 on Windows doesn't have that
problem. I'm not sure if it's a recent regression or if it's a Mac-specific issue.

We need to streamline related bugs. Let's make this as a dupe and file a new bug
on IMAP folder search. (bug 284856 was just filed)
