commit d8ce3f60bad3ebaa0888b35f85ab1a211714bb14
Author: Stephan Bergmann <sberg...@redhat.com>

    Fix ooo::vba::parseKeyEvent
    
    Use rtl::isAscii* functions (correctly operating on OUString elements) 
instead
    of truncating OUString elements to char and then using <ctype.h> is* 
functions
    (which, in addition, for one can cause UB for char arguments when char is
    singed, and for another can be locale-dependent).
    
    (Found when auditing uses of <ctype.h> is* functions.)
