/**
* An AccentComposer translates from UniCode's combining accent forms
* into composite characters with embedded accents. This is necessary
* on Mac OS X and 9, which return the combining accent forms as
* filenames from many places, including File.list() and FileDialog.
*
* <p> The AccentComposer class is both a general-purpose compositer
* and a Singleton set of default composition mappings. The Singleton
* is initialized with a set of mappings that covers the typical
* accents one will see in a Roman or Latin-1 situation on Mac OS 9 or
* X. It does not cover all possible cases for all of UniCode.
* However, since you can add additional mappings, or replace the
* defaults, you can easily control how many or which accents will be
* composited.
*
* <p> The AccentComposer.composeAccents() method is
* called by the Mac-specific PathnameFormats defined in
* "PathnameFormat.java". In reality, only Mac OS 9 and X need this,
* but it's not worth the effort to split out Mac OS into pre-9, 9,
* and X sub-versions. At least not yet.
*
* <p> Note that there is no
* AccentDecomposer, and no such capability in this class. This is
* unnecessary for my uses, since the file-system itself happily takes
* composited characters and turns them into combining form. Good
* thing, too, because decomposing accented characters is more
* difficult than combining accents and characters together.
*
* <p>Personally, I think it's lame that Java doesn't have a class in
* "java.text" that performs compositing. There's Collator and
* different ways of comparing accented Strings, but no way to
* actually translate to and from between the composited and combining
* forms.
