> Deviations from platform behavior should be a rare exception, not a rule. For example, if line breaking worked differently in Apple Mail and Safari than in other Mac OS X applications, that would be a problem for users.

It seems that almost all platforms' WebKit are by default using ICU for line breaking of non-ASCII characters, except qt (using QtCore/QTextBoundaryFinder), wince (not using any library) and brew (not using any library). Gtk has two choices and ICU is the default. Line breaking between ASCII characters is handled in WebCore/platform/break_lines.cpp for all platforms.

If we want to keep platform behavior, do you think we should let all platforms use their own platform specific line-breaking libraries? I think this would degrade performance. I believe this is the main reason that we are not using any library for ASCII character line-breaking.
