I see what you mean, does seem like a useful addition:

(assoc m k (apply f (k m) args)))

vs.

Does clojure come with a built-in regex replace method? I see ones for
re-split, re-seq etc. but nothing for a simple replace, I've been using:

There seems to be two separate issues regarding character sets in Clojure:
1) What encoding should clojure use to read/write to *in*, *out*, and *err*?
2) What encoding should clojure's use to load .clj files.
For 1) Clojure currently uses UTF-8 - this is hardcoded in the constants for
