> The ISOLatin1AccentFilter is removing accents from accented characters in the ISO Latin
1 character set.
> It does what it does and there is no bug with it.
> It would be nicer, though, if there was a more comprehensive version of this code that
included not just ISO-Latin-1 (ISO-8859-1) but the entire Latin 1 and Latin Extended A unicode
blocks.
> See: http://en.wikipedia.org/wiki/Latin-1_Supplement_unicode_block
> See: http://en.wikipedia.org/wiki/Latin_Extended-A_unicode_block
> That way, all languages using roman characters are covered.
> A new class, ISOLatinAccentFilter is attached. It is intended to supercede ISOLatin1AccentFilter
which should get deprecated.
