Use EXT-PLIST argument, e.g.,

  (org-export-string-as string 'ascii nil '(:ascii-charset utf-8))
  (org-export-string-as string 'ascii nil '(:ascii-charset latin1))
  (org-export-string-as string 'ascii nil '(:ascii-charset ascii))

We could accept any symbol, try to (require 'ox-SYMBOL) and then

  (org-export-string-as string SYMBOL)
