Change emoji font to the Windows style

The only workaround I've found is to use accessibility zoom; old man style.

The problem persists in Yosemite 10.10.3 with the new Emoji picker.

Yes and no. You can change the default emoji font used by Mac OS X, but I don't think you can change it to Google's Noto fonts, although that may depend on your version of OS X.

Basically if you have a font file in .ttf format that contains emoji, you can replace Apple's emoji font with that font using the following steps:

1. Ignore the default location for Apple's emoji located in system/library/fonts. In other words, leave this alone.
2. Obtain another emoji font file. HINT: The emojione font is similar to Google's.
3. Rename your other emoji ttf font file to Apple Color Emoji.ttf
4. Move the newly renamed font file to the /library/fonts folder.

I know the above process works for El Capitan, but your situation may be different.
