ligature describing need for extra space below and above

this is not metacity issue, this is problem from fonts

reason behind this is font metrics of Meera

Rachana: Ascent: 1638, Descent: 410
Meera:  Ascent: 1147, Descent: 901
Lohit:  Ascent: 650, Descent: 374

some ligature of Meera requires this space

see bug #523454
Comment 6 Praveen Arimbrathodiyil 2010-05-14 01:55:25 EDT
I don't think it is specific to Meera of  Malayalam, we noticed problems with Panjabi and Telugu as well. Latin characters along with Panjabi was even getting cut at the bottom.
Comment 7 Praveen Arimbrathodiyil 2010-05-14 02:11:29 EDT
Title bar is of expected size with other fonts, but we need to fix it for Meera as well.

We know Ascent and Descent of Meera differs from other fonts, but if you look at the values you have given, even though the Descent is more Ascent is proportionally less. So how would that affect this bug?
Comment 8 fujiwara 2010-05-14 02:25:30 EDT
metacity calculates the text height == pango_font_metrics ascent (metrics) + descent (metrics) and my understanding is the metacity is right.
Comment 9 Bill Nottingham 2010-05-17 11:10:11 EDT
Should this bug be reassigned?
Comment 10 Praveen Arimbrathodiyil 2010-06-10 04:38:07 EDT
for Meera this can be fixed by changing the fontconfig configuration.

current configuration is,

<match target="font">
        <test name="family">
        <edit name="matrix" mode="assign">

<times> and </times> should be removed.
