What is the use of the character preset feature?
A huge gain of time and much more less number of requests to the web server. Of course if you know how to use it efficiently. With the dichotomy technique, in order to find the representation of a character in ASCII you need to go through all the existing 256 characters in the ASCII table. It would require thus 8 requests to the web server by character. Knowing this, let’s say you have a sentence that contains 100 characters that would make about 800 requests. If we consider that in average the round trip takes half a second, it would take 400 seconds, so 6 minutes and 40 seconds. Quite some time, isn’t? So I asked myself, how can I optimize it? It came to me that most of the time the strings that I was trying to get were predictable when it comes to the type of characters they contained. That is to say that beforehand I was able to know that in some cases a string would be only alphabetic characters with spaces. So why use the full set of characters (256) when in fact I needed to sear
