724335 - Rendering of service-mark entity is really ugly

Status: RESOLVED DUPLICATE of bug 560472

(Core :: Layout: Text and Fonts, defect)

Description

[Kyle Simpson]

Attachment: screenshot of service-mark entity rendering in Firefox Aurora (11), Chrome 16, and Safari 5.2

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:11.0a2) Gecko/20120131 Firefox/11.0a2
Build ID: 20120131042011

Steps to reproduce:

I use this entity: & #8480; on a normal html page.


Actual results:

it renders really horribly ugly, only in Firefox, but renders sanely as expected in Chrome and Safari. See the screenshot attached.


Expected results:

i expect that the rendering of a server-mark entity should be nearly identical to the quality that the & trade; trademark entity renders.

That character is not present in the default font being used (or, probably, most fonts used by typical pages), so what you'll see depends on the font we happen to find during font fallback. On my Mac, it picks DejaVu Sans, which looks pretty similar to the Chrome & Safari renderings in your screenshot, but this will depend what fonts you happen to have installed.

(You can find out what font is actually being chosen by using the fontinfo add-on.)

This is basically an example of the behavior described in bug 560472. It looks like we'll be addressing this in bug 705594, which should help by providing more standardized and predictable fallback behavior for most characters.
