I was tired that htop didn't showed up the info as is, and started to google about it.
Aparently there's an issue with the drawing stuff for bold and not-bold fonts, and most workarounds consists on making htop showing things on black and white.
Then, lazyness came to my mind and used:
Wala! It worked, and showed htop with colors! 12 colors of course, but I don't need more!!
So after that I just echoed that line to my ~/.bash_aliases and is pretty much done for a while, at least for me. It works!
