Unicode nearing 50% of the web
January 28, 2010
About 18 months ago, we published a
graph
showing that
Unicode
on the web had just exceeded all other encodings of text on the web. The growth since then has been even more dramatic.
Web pages can use a variety of different character encodings, like ASCII, Latin-1, or Windows 1252 or Unicode. Most encodings can only represent a few languages, but Unicode can represent thousands: from Arabic to Chinese to Zulu. We have long used Unicode as the internal format for all the text we search: any other encoding is first converted to Unicode for processing.
This graph is from Google internal data, based on our indexing of web pages, and thus may vary somewhat from what other search engines find. However, the trends are pretty clear, and the continued rise in use of Unicode makes it even easier to do the processing for the many
languages
that we cover.
Searching for "nancials"?
Unicode is growing both in usage and in character coverage. We recently upgraded to the latest version of Unicode,
version 5.2
(via
ICU
and
CLDR
). This adds over 6,600 new characters: some of mostly academic interest, such as Egyptian Hieroglyphs, but many others for living languages.
We're constantly improving our handling of existing characters. For example, the characters "fi" can either be represented as two characters ("f" and "i"), or a special display form "fi". A Google search for [financials] or [office] used to not see these as equivalent — to the software they would just look like *nancials and of*ce. There are thousands of characters like this, and they occur in surprisingly many pages on the web, especially generated PDF documents.
But no longer — after extensive testing, we just recently turned on support for these and thousands of other characters; your searches will now also find these documents. Further steps in our mission to organize the world's information and make it universally accessible and useful.
And we're angling for a party when Unicode hits 50%!
