With this change, different languages can have a different minimum
length for suffix and prefixes when hyphenating. Previously, the
defaults used for English, 2 and 3, were used for every language.

This adds better support for Arabic script languages, Armenian,
Catalan, Hebrew, Kannada, Malayalam, Polish, Tamil, and Telugu by
adding various hyphenation types and edits appropriate for the

For Arabic script languages, soft hyphens act transparently with
regard to joining: If a line is broken at a soft hyphen where the two
characters around the soft hyphen were joining each other before,
they will continue to appear joining if the line is broken at the
soft hyphen and a hyphen glyph is inserted. This is needed for
Central Asian languages such as Uighur.

For Armenian, U+058A ARMENIAN HYPHEN is used for line breaks caused
by either automatic hyphenation or soft hyphens.

For Catalan, nonstandard line breaks are implemented for "l·l", which
hyphenates as "l-/l".

For Polish, when there is a line break at a hyphen, the hyphen is
repeated at the next line.

For the South Indic languages, when breaks happen due to soft breaks
or automatic hyphenation, no visible hyphen is inserted, although a
penalty is added.

For Hebrew, support for using U+05BE HEBREW PUNCTUATION MAQAF has
been implemented, but it's turned off pending confirmation of

Also, hard hyphens, which previously had no penalty added for
breaking the line after them, now have the same penalty as an
automatic or soft break, with the difference that no hyphen is
inserted when they break.

Finally, some bugs have been fixed with hyphenating multiscript and
multi-font words.
