Improving Unicode support in SBCL

by Krzysztof Drewniak for Steel Bank Common Lisp

Currently, SBCL does not have very good support for working with Unicode text. In order to improve SBCL's Unicode support, I propose to create a 'sb-unicode' package that will contain implementations of the algorithms used in the Unicode standard and provide other facilities for working with Unicode text. I also propose to implement a "Unicode string" type, which will allow functions in the 'cl' package to operate correctly and transparently on Unicode data.
