Comment 15 Harshula Jayasuriya 2009-07-21 07:44:33 UTC
Hi,

I recently noticed that Al-Mayanna (U+0DB8,U+0DCA) on Fedora 11 looks incorrect:
https://bugzilla.redhat.com/attachment.cgi?id=142050

It looks like a Mayanna (U+0DB8) which has been compressed vertically and then an is-pilla (U+0DD2) placed on it. The particular is-pilla glyph that has been used is meant only for glyphs without an ascender. Furthermore, due to this change Al-Mayanna now looks inconsistent with the Al (Virama) form of all the other letters that contain an ascender.

My view is that Al-Mayanna (U+0DB8,U+0DCA) looked *more* correct before this change. i.e. This change causes a regression.

Furthermore, I think these are all valid Al-Mayanna glyphs:
* https://bugzilla.redhat.com/attachment.cgi?id=135992
* https://bugzilla.redhat.com/attachment.cgi?id=135988
* https://bugzilla.redhat.com/attachment.cgi?id=354436

Whereas, this is a Miyanna:
https://bugzilla.redhat.com/attachment.cgi?id=354437

I think the difference between the Al-Mayanna and Miyanna is the sharp point at the top left corner of the Al-Mayanna. I will double check on this.

It would appear that Bug 209572 contains most of the discussion regarding this particular bug.

My recommendation is to revert back to the previous Al-Mayanna glyph.

cya,

showing all combination involved in bug

hi harshula,

i think whatever we have presently is correct? i.e style of showing cap on MAYANNA is same, sharp edge is present

also danishka has also added Comment #12 that all thing are ok and same thing is available from fc6

do you want it to revert back as it was previously previously?

Hi Pravin,

Comment 18 Harshula Jayasuriya 2009-07-22 05:52:19 UTC
I've added Danishka to the CC list.

Hi Danishka,

Can you please have a look at ම් (Al-Mayanna) on Fedora. Do you think that looks correct? Have a look at ච්, ට්, ඩ්, ඬ්, බ්, ම්, ඹ්, ව්, which one do you think looks out of place?

In https://bugzilla.redhat.com/show_bug.cgi?id=206001#c12 you say "working on RHEL 5.1". It clearly looks incorrect. The Mayanna has been compressed vertically and an Is-Pilla glyph placed on top.

cya,

Comment 19 Danishka Navin 2009-07-22 16:36:07 UTC
Hi Harshula,

Right now i am not on RHEL 

 ම් (Al-Mayanna) is fine for me on Fedora 11

but i want to double check " ච්, ට්, ඩ්, ඬ්, බ්, ඹ්, ව්" with a language expert. 

cya.

Comment 20 Harshula Jayasuriya 2009-07-23 01:56:20 UTC
Hi Danishka,

1) Can you please describe what is wrong with the original Al-Mayanna:
https://bugzilla.redhat.com/attachment.cgi?id=135992

2) Can you please describe any problems with this Al-Mayanna:
https://bugzilla.redhat.com/attachment.cgi?id=354436

Hi Pravin,

I agree with Harshula.

Yes we need to revert al-mayanna

pls note, it is hard to find the difference between ව and ව් .
we need to modify "ච්, ට්, ඩ්, ඬ්, බ්, ඹ්, ව්"  near future.
