you're welcome.
however, i don't think kanji space shouldn't be quoted.
the purpose of the function is to determine if the string needs quoting for
rc's benefit. (there are a number of space characters and other potentially-confusing
stuff in unicode that rc does not interpret as whitespace.)
the function you're looking for could be called "needshumanquote" and
could be written like this
int
needshumanquote(int r)
{
if(r <= ' ')
return 1;
if(r < 0x80 && strchr("`^#*[]=|\\?${}()'<>&;", r))
return 1;
if(!isalpharune(r))
return 1;
return 0;
}
a better version of this function could be written with the a function
isspacerune. (i've got a script which generates this table from UnicodeData.txt.)
there's a patch for needsrcquote in /n/sources/patch/needsrcquote.
