The patch looks much better. There is one remaining problem:

+ int pos = sizeof(html_encoded_symbols)/sizeof(html_encoded_symbols[0]);
+ float step = pos/2;
+ int dir = +1;
+ do
+ {
+ const char *encoded_symbol;
+ pos += -dir*ceil(step);

Using float here is definitely not needed, esp. that you always use
ceil() on it. You've made it more complicated than it really is. See [1]
for an example. Also feel free to send linear search with FIXME comment.
That's fine for the first iteration patch.
