Seems like it's safe:
* http://userguide.icu-project.org/icufaq#TOC-How-is-the-ICU-licensed-
How is the ICU licensed?
The ICU projects since ICU 1.8.1 and ICU4J 1.3.1 are covered
by the ICU license , a simple, permissive non-copyleft free
software license, compatible with the GNU GPL. The ICU
license is identical to the version of the X license that was
formerly available at http://www.x.org/Downloads_terms.html .
(This site no longer exists, but can still be retrieved
through internet archive services)
The ICU license is intended to allow ICU to be included
both in free software projects and in proprietary or
commercial products.
They use Perl string escapes and regex notation:
* http://userguide.icu-project.org/strings/unicodeset#TOC-UnicodeSet-Patterns
* http://userguide.icu-project.org/strings/regexp
Plus, they've added a /w flag to control \b behaviour,
a frequent and subtle pain-in-the-posterior.
ICU seems worth looking over at least, even if it's just to learn
things, not to use things. These also caught my interest:
* http://userguide.icu-project.org/boundaryanalysis
* http://userguide.icu-project.org/transforms/general
* http://userguide.icu-project.org/collation/concepts
* http://userguide.icu-project.org/collation/customization
Thanks, Karl.
