468064 - Bad reply if the from name has special characters (á, í...)

Status: RESOLVED DUPLICATE of bug 254519

(Thunderbird :: Message Compose Window, defect)

Description

[sanfermines]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; es-ES; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4
Build Identifier: versión 2.0.0.18 (20081105)

If the from name has some special characters like (á, í) when you try to reply the e-mail Thunderbird thinks there are two senders. 

I have made a screenshot since it is easier to see:

If I see the e-mail with ctrl+u I get:
From: =?iso-8859-1?Q?Echeverr=EDa_Jaurrieta=2C_Mikel?=


Reproducible: Couldn't Reproduce

Steps to Reproduce:
I have tried to reproduce it but I couldn't. I did:
1. Creating and account with a name that has special characters
2. Sending an e-mail with that account

Actual Results:  
I get different results depending on what mail provider I use. 
If I use gmail, it works properly, and I get:
From: "=?ISO-8859-1?Q?Gonz=E1lez_Casco,_Mar=EDa?="

If I use my business e-mail when I click reply it doesn't try to reply two sender, but it doesn't show properly the name. I get:
From: =?iso-8859-1?Q?Gonz=E1lez_Casco=2C_Mar=EDa?=

Expected Results:  
I expected it works in every case as it does with gmail account
I have problems with my business e-mail account and with other mails that are sent to me (so it is not only a problem of my e-mail provider)
