handy.h: No need to call fcns to compute if ASCII

Only the characters whose ordinals are 0-127 are ASCII.  This is
trivially computed by the macro, so no need to call is_uni_ascii() to do
this.  Also, since ASCII characters are the same when represented in
utf8 or not, the utf8 function call is also superfluous.
