ICU has code which maps a code point to a script. There is also code to 
identify runs of text all in the same script, taking neutral characters 
into account. For example, Arabic words separated by spaces will be 
returned as a single run.

(The ICU code which maps code points to script uses the general Unicode 
properties mechanism, which pulls in quite a bit of ICU; I have a version 
of this code which uses a table built by an ICU application so you can 
avoid the direct ICU dependencies...)
