Fira Code uses the empty set character (∅) for zero. This mistake cost me a correct answer on a math test in 12th grade because I made the wrong slash.

Either that, or I made the correct slash and my teacher interpreted it incorrectly!

it's also inconvenient for Norwegians and Danes, since Ø is part of our alphabet. Slightly jealous of Sweden since they write it like Ö instead... Either way, big fan of dotted zeros for that reason.

Yeah, dot in the middle is the best option, also better aligns with the whole circular concept of the glyph as opposed to the straight slash line
