: <dfn>Column</dfn>
:: The zero-based indexed offset within a line of the generated code. How this offset is
measured can depend on the content type. For JavaScript and CSS based source
maps, they are defined to be in UTF-16 code units analogous to JavaScript string indices. That means
that "A" (`LATIN CAPITAL LETTER A`) measures as 1 code unit, and "🔥" (`FIRE`) measures as 2 code
units. For WebAssembly, columns are defined as byte offsets from the beginning of the binary
content (and there is only one group representing a line). Source maps for other content types
may diverge from this.
