'character and 'string-char are aliases in most instances.  After
poking around a bit in 2.6.x, the only possible gotcha I found was

(array-element-type (make-array 10 :element-type 'character)) -> 'string-char

string-char is currently out of 2.7, but I'll probably put it in as
deftyped to character for cltl1 compliance before release.  2.7
appears fully ansi compliant in this regard as far as I can tell. 

Take care,
