Description

[Jan Merka]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041119
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041119

Mozilla browser (1.7.3 and several previous versions at least) does not display
some Unicode characters and leaves either a blank space instead or blanks more
spaces up to the rest of the paragraph (until a next Unicode character only?).

For example, the symbols: lambda λ, theta θ, sigma σ, etc.

Reproducible: Always
Steps to Reproduce:
1. Create a simple web page with, for example, the symbols: lambda λ, theta
θ, sigma σ, etc.
2. View it in the Mozilla browser.


Actual Results:  
The Unicode characters are not displayed.

Expected Results:  
Display the symbols.

Worksforme in a current trunk build.  Which exact build do you use (what does
about:buildconfig say)?  This sounds like a bug in a font or font subsystem.

Here it is:

OK.  So it's either an XFT bug or a bug in the font XFT is using....  What XFT
version do you have installed?

Comment 4

[Jan Merka]

The installed xft is part of the XFree86 version 4.4.0 and all fonts accompany
the XFree86 version 4.4.0 (got installed 100dpi fonts, scalable fonts (Type 1
and ps fonts I guess), and cyrilic fonts).

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
