Pros
Pro Clashing characters are easily distinguishable

Pro Bold font is the same width as the regular weight font

Cons
Con No Cyrillic glyphs
There are no Cyrillic glyphs in Envy Code R which may be an issue for Russian users.

Con Lowercase "w" is distracting
The lowercase "w" is a bit distinct looking due to the narrow nature of the font. This could cause a distraction to some users.
Con Pointless to use this for legibility unless you're on an exceptionally small screen device
The tiny point size does not scale well. It's designed for a singular purpose and does well for that, but unless you're working around those limitations the poor readability will slow down your work.
Con Not as pretty as other fonts
Other options look better than Tiny Font at bigger sizes.
