JVM parity: unchecked-char -> char, pr of infinities -> ##Inf

Browse source 
Allowlist review found three addressable divergences:
- unchecked-char returned a number; the JVM returns a char.
- the readable printer (pr-str, coll elements, the -e/REPL printer) rendered
  infinities as Infinity/inf; Clojure's readable form is ##Inf/##-Inf/##NaN
  (str/print still gives Infinity). So (pr-str ##Inf) => ##Inf, (str [##Inf]) =>
  [##Inf], (str ##Inf) => Infinity.

Corpus 2695->2698; allowlist 43->40 (drop the 3 now-passing entries). Re-minted.
