Chromium renders Korean text (Hangul) illegibly

[Paul]

Install chromium-browser and visit a page with Korean text, e.g.:

http://ko.wikipedia.org/wiki/%EC%84%A0%ED%92%8D%EA%B8%B0_%EC%82%AC%EB%A7%9D%EC%84%A4

Hangul text inside the rendering area (but not outside it, e.g. tabs) is smashed together; see attached screenshot.

Ubuntu 13.04, Chromium 25.0.1364.160.

I can't reproduce on 25.0.1364.160 .

Do any other pages cause the problem? Is it all KO text in web pages, or only some typefaces?

[Paul (i41bktob-launchpad-net)]

When a page is affected, all Hangul on that page renders improperly (except text-as-images, which is fine of course). I think you're right about fonts; pages that use NanumGothic seem to be immune, whereas when the text is rendered using DejaVu Sans, the problem occurs.

Other affected sites:

http://2013chungju.org/
http://www.archives.go.kr/next/main.do
http://dev.naver.com/projects/nanumfont
and any page source viewed through the built-in source viewer

Not affected:

http://hangeul.naver.com/index.nhn

This is a clean install of Raring, with only the standard fonts installed.

Sorry can't remember the exact link, but in one of the chromium bug reports someone suggested to install the fonts-unfonts-core package and that solved it for me.

[Damien Genet (damien-genet)]

Installing fonts-unfonts-core didn't help for me.

Same experience. I have a fresh installation of raring i386

$ dpkg -l | grep "chromium-browser "
ii chromium-browser 28.0.1500.52-0ubuntu1.13.04.3 i386 Chromium browser

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=13.04

This bug still affects Saucy (Chromium 29.0.1547.65-0ubuntu2) after an upgrade from Raring, with only default fonts installed.

[Joonas Saarinen (jza)]

The issue is tracked upstream and it is suggested that:

"This is caused by incorrect "horizontal advance widths" in the "hmtx" (Horizontal Matrix) table in "WenQuanYi Micro Hei", causing the Hangul glyphs to overlap one another. Most people usually see this bug in WenQuanYi Micro Hei manifest itself in Chromium but not elsewhere. Strange."

According to https://bugs.chromium.org/p/chromium/issues/detail?id=233851 this was a bug in the font itself, and has been fixed since then.
