The character is not so new. It was just still missing in Uniode 3.2 and was added in Unicode, now years ago.
Unicode 6 is about to be released (there's already been Unicode 4.1, Unicode 5, Unicode 5.1, and the current Uniode
5.2... much time in fact when compared to the development of web browsers to include updated tables for line-
breaking properties, and for font renderers and text layout engines to add support for many new scripts and many new
punctuations and symbols).

Note that browsers and font renderers or layour engines are updated much more frequently than fonts (it's much
easier because OpentType font development is a really complex task that requires very specific skills and expertise,
also because almost all high-quality fonts are generally heavily protected by their licence).
