Status: RESOLVED DUPLICATE of bug 1390015

(Thunderbird :: Untriaged, defect)

Description

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180327223059

Steps to reproduce:

I received an order confirmation email from ebay, which shows the subject like one of the three below:
Subject: =?UTF-8?Q?=E2=9C=85_Order_confirmed:_Charles_Austen_Air_P...?=
Subject: =?UTF-8?Q?=E2=9C=85_Order_confirmed:_15-100mm_Forstner_Wo...?=
Subject: =?UTF-8?Q?=E2=9C=85_Order_confirmed:_Pure_Evoke_1xt_DAB_R...?=
All of these have the same problem.
Version 52.7.0 (64-bit), Manjaro - Rolling


Actual results:

The =?UTF-8?Q?=E2=9C=85_ seems to generate a "tick" character 8x larger than the rest of the text:
1. If I search for messages, the tick overwrites parts of the "Subject" display.
2. If I view an email with such a tick, the tick appears in the tab text, displacing the text, and it appears in the email subject line as an oversized tick.
3. If I print the email, the tick alsso appears 8x expected size, in the Subject line of the print.


Expected results:

I would expect a tick to appear, but at the same size at the other characters.
It appears to be a rendering-only problem, not one of substance.
Thanks guys!
