Bug 25464 – Improve font fallback for 'common' characters in Chromium Win port

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Jungshik Shin]

This is to fix Chromium bug ( http://crbug.com/3536 http://crbug.com/1716 and related issues not yet reported). 

I'll upload the patch (at http://codereview.chromium.org/99146) along with a layout test/result.

Looks good except for style comments:

> +UScriptCode getScriptBasedOnUnicodeBlock(int ucs4)

Add static modifier.

> +UScriptCode getScript(int ucs4)

Ditto.

> +    if (script <= USCRIPT_INHERITED || U_FAILURE(err))
> +      script = getScriptBasedOnUnicodeBlock(ucs4);

4 spaces.

They're currently inside an anonymous namespace. I'm aware that WebKit does not use anonymous namespace elsewhere. Do you think we have to follow the convention in this file?

I'll upload a check-in-ready patch once I hear back about the namespace issue above.

Ah, I didn't see anonymous namespace in the context of the patch. LGTM then.

same as the previous except the test location

I moved two tests I'm adding to fast/text/international from fast/text.
Transferring r+.

Your patch was missing pixel results, but I added them before committing.
