html_quote() - also quote chars > 127

Anonymous — Sat, 23 Mar 2002 15:26:52 -0000

Would be a useful feature, I think, when html_quote
also would be able to quote chars with a value > 127.

A diff on cgifunc.c in libstrfunc 7.4 that is adding
that feature:

appsrv:/usr/src/libstrfunc-7.4 # diff ./cgifunc.c
~/cgifunc.c
376a377
> int i;
382c383,391
< nc = countchar2(s, "\&quot;&<>");
---
> /* count the number of characters to quote */
> nc=i=0;
> while(*(s+i))
> {
> if(strchr("\&quot;&<>", *(s+i))) nc++;
> if(*(s+i) < 0) nc++;
> i++;
> }
> /* calculate number of bytes to allocate for
quoted string */
384a394
> /* perform allocation for destination string */
388a399
> /* if nothing to quote, simply copy the input
string */
397a409
> /* perform quoting for ", <, >, & and all
chars > 127 */
409c421,426
< *p++ = sc; continue;
---
> if( (int)sc < 0)
> {
> sprintf(p, "&#%
u;", (unsigned char)s
> p+=6;
> } else *p++ = sc;
> continue;
