1235444 - Searching accentuated characters gives no results when e-mails are encoded in quoted-printable

Status: RESOLVED DUPLICATE of bug 506064

(MailNews Core :: Search, defect)

Description

[Jean-Philippe Fleury]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20151210084639

Steps to reproduce:

I have an IMAP account with all messages available offline. I receive messages from a discussion group whose messages are in UTF-8 with both plain text and HTML parts, and encoded in quoted-printable:

    Content-Type: text/plain; charset=UTF-8
    Content-Transfer-Encoding: quoted-printable
    
    [...]
    
    Content-Type: text/html; charset=UTF-8
    Content-Transfer-Encoding: quoted-printable

The bug occurs when I search words containing accentuated characters in the e-mail body (but not in the subject) using the search box in the quick filter toolbar or the advanced search (right click on a folder and select "Search Messages...").


Actual results:

For example, if I search the word "coordonnées" in the body, no results are found. To find occurrences of this word, I must encode it in quoted-printable, i.e. "coordonn=C3=A9es" (so as it appears in the e-mail source code).


Expected results:

I should not have to encode the search terms. I should have results for the term "coordonnées".

Note that this problem doesn't occur with the global search.

Could this bug be related to the report #481616 ?
