It not, see this, I add a werror before VARINFO return:
class VARINFO(mixed v)/*{{{*/
{
string _sprintf(int t)
{
if(t=='O'||t=='s'){
string out="";
string s=sprintf("%O",v);
for(int i=0;i<sizeof(s);i++){
if(i+3<sizeof(s)&&s[i]=='\'
&&s[i+1]>='0'&&s[i+1]<='9'
&&s[i+2]>='0'&&s[i+2]<='9'
&&s[i+3]>='0'&&s[i+3]<='9'
){
out+=sprintf("%c",((s[i+1]-'0')*8+(s[i+2]-'0'))*8+(s[i+3]-'0'));
i+=3;
}else
if(i+1<sizeof(s)&&s[i]=='"'&&s[i+1]=='"'){
i+=1;
}else{
out+=sprintf("%c",s[i]);
}
}
werror("%s\n",out);
return out;
}
}
}/*}}}*/
void main()
{
write("%O\n",VARINFO((["大家好":1])));
}
the output is:
[<peterpan[at]brain> ~]$ pike varinfo.pike
([ /* 1 element */
"大家好": 1
])
([ /* 1 element */
"\u00e5\u00a4\u00a7\u00e5\u00ae\u00b6\u00e5\u00a5\u00bd": 1
])
it is escaped after VARINFO return.
