IDE for Windows like the official one?

One thing to keep in mine when loading fonts -- they don't always render characters the same.  Consola's pipe character "|" may not render fully to the top or bottom of a line, giving that gap that you're seeing when they're stacked one on top of the other.

The above screenshot is taken from Word, and it shows that same "pixelated" gaps in the characters.
