Padauk font for Burmese/Myanmar breaks ASCII/Latin rendering in Myanmar wikipedia

Project Member Reported by js...@chromium.org, Aug 11 2016 
Go to https://my.wikipedia.org/wiki/Wikipedia:Font.  The English portion is totally messed up (a lot of overlapping glyphs). 

OTOH, http://my.wikipedia.org is fine (mostly Burmese text). 

my wikipedia specifies a long list of fonts in font-family. 

mm3web,Myanmar3,TharLon, "Masterpiece Uni Sans",Parabaik,Yunghkio,Thanlwin,"Win Uni Innwa",Padauk ,"MyMyanmar Unicode","Myanmar Text","WinUni Innwa",Myanmar2;

Padauk is the only font available on Chrome OS and is picked up to render both ASCII and Myanmar characters. (CrOS has both Padauk and Noto Sans Myanmar).

I left alone Padauk to have multiple fonts for Myanmar (until we have our own Noto Serif Myanmar), but it looks like we'd better remove it. 

In the meantime, I'll try to use 'Padauk' with hb-* to render ASCII text. 

I'm assigning this to myself to get rid of Padauk from CrOS.

http://jungshik.github.io/cr/bugs/637039/  : test page. (it uses web fonts. ) 

Not just Chrome on Linux/CrOS but also Chrome on Mac and Firefox have the same issue. 

The page uses both Padauk 2.50 and Padauk 2.80. Both fonts have the same issue. 

a vertical metric is kinda broken?   

However, gedit does not have an issue.

hb-view is also fine with multiline text input. 

Attached is a screenshot of Mac Chrome rendering http://jungshik.github.io/cr/bugs/637039/

I've just added a 3rd line to the test file as a control. That line does not have 'font-family' specified.

Delete Padauk font

When Padauk is used for ASCII/Latin text, a series of lines overlap
each other instead of progressing downward

BUG= chromium:637039 
TEST=https://my.wikipedia.org/wiki/Wikipedia:Font is legible (no overlap
     of lines).
TEST=build_image: /usr/share/fonts does not have my-padauk

Padauk is removed from CrOS. Now a real issue has to be taken care of.

Comment 6 by drott@chromium.org, Sep 1 2016 

What "real issue" remains? See also  issue 637464  where we have some issues with Padauk on a Galaxy Note 2.

"The" real issue is to figure out why Padauk behaves in such a strange manner when rendering Latin. Thank you for figuring that out in  bug 637464 .
