strings seem to be made of uint8 characters. runes seem to be larger. Does this mean there are two sets of functions for dealing with these two kinds of data? In particular I am looking for isdigit. There seems to be one that works on runes, but not one that works on ASCII.

strings are immutable byte slices.
runes seem to be larger.
yes, the size of a rune is larger than a byte.

Yes

If you have a value as a byte, you may need to convert it to a rune, Go Playground - The Go Programming Language
