google logo wonky o's different coloursGoogle has recently started using Unicode software because of big advantages. They have found that Unicode is growing at an explosive rate, and they should integrate it into their software in order to make more documents and pages turn up in search results.

What this means to normal Google users is that new results should be showing up. For programmers, this means you should think of switching to Unicode as the majority group of people now use Unicode, albeit under half of all web encoding. But it is growing so fast that within a few years time, it could be 65%+ of users, programmers and pages using Unicode.

The search engine leader, Google thinks that Unicode has earned itself the encoding ‘giant’ tag. If you look at the graph below, Unicode is the blue one that rises steeply, if you can’t see the key. The Graph shows the percentage of web documents and pages in different encodings.

Basically, as Unicode gets more popular, more characters and more languages will be understood. Mark Davies from the Google team was talking about one of the basic concepts. Before the Unicode integration into their software, the two letters ‘fi’ would not show up as two different characters, but as a special display form. This means that the Google software would not recognise this, which meant if you searched for ‘office’, ‘Finland’ or ‘finance’, Google would only see this as ‘of*ce’, ‘*nland’ or ‘*nance’. Now that it can see this and other ‘special display forms’ and less common characters, Google can provide better results. It's great that the Google team keep making their search engine better day by day; it's why they are the best and plan to stay that way.
