Pro Different typefaces

Pro Looks great on Ubuntu 14.04
Code New Roman has been tested on cheap Dell Inspiron with Ubuntu 14.04 installed and looks great on gtk-based apps such as Sublime Text, Geany, and TextAdept. It's also great on Qt-based apps such as KDevelop and Spyder. For electron/nwjs-based applications, it looks great on Visual Studio Code and Brackets, but has yet been tested on atom. However, it looks horrible on Swing-based apps such as Netbeans or Jetbrains' IDE.
Pro Multilingual
Code New Roman is available in English.
Pro Highly anti-aliased
This means that jaggies are reduced, making the line smoother.
Cons
Con Pixelated
This is, of course, intentional; but it can be hard to look at compared to other smooth mono-space fonts.
Con Smallest font sizes hard to read
Fonts less than 11pt start to fail readability tests. 9pt specifically has an additional issue where brackets don't align.
Con Not really good in all font-sizes
Completely clean pixels, no anti-aliasing so its best viewed in (n*12) pixel size.
Bold font-weight is not really good because of small padding between them.
Con No updates
No updates or original publisher. Mostly edited and uploaded by many designers because of its OFL license.
Con Looks bad in Windows
Too much anti-aliased in Windows.
