119397 - Last resort font characters are rendered displaced vertically

Status: VERIFIED WORKSFORME

(Core :: Internationalization, defect)

Description

[Greg K.]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:0.9.7) Gecko/20011221
BuildID:    2001122106

Fizzilla falls back to a font of last resort when it is necessary to display a
glyph not in the desired font for the given text, but displaces the fallback
glyph vertically.


Reproducible: Always
Steps to Reproduce:
1. Install the Code2000 font
2. Access the HTML test case in Mozilla

Actual Results:  The glyph, ѣ is unavailable in any of the installed
Cyrillic Language Kit fonts under Mac OS X. Fizzilla falls back to Code2000 and
displays the glyph from that font, but places the glyph approximately one inch
below the rest of the line.

Expected Results:  The glyph in question from Code 2000 should have been
displayed on the same baseline with no offset with respect to the other characters.

The Code2000 font (available at [http://home.att.net/~jameskass/CODE2000.ZIP])
is a nearly-complete Unicode font that can be installed under Mac OS X. For
certain Cyrillic glyphs unavailable in an installed Cyrillic Language Kit font,
Fizzilla falls back to Code2000.

I added the font CODE2000.TTF to my libary | font directory, and running the
attached test case, it showing a little difference than the reporter's screen
shot but looks like still showing vertically on 01-10 trunk build. 
Confirming... a screen shot will be followed.

cc ftang and nhotta.

give to nhotta to debug.

Note that the actual vertical position of the last-resort glyph will vary from
access to access for some reason, though it never actually ends up in the right
position...it's always off to one degree or another.
