what does "column" mean?

The sourcemap spec is defined in terms of column and line numbers, but it
doesn't define what a column means. Is this measured in Unicode code points
or 16-bit code units?

If implementors aren't thinking about this, I'd guess that we're working in
code units by default, at least for JavaScript and Java.

What do compilers do?
