           Summary: [Gtk] Verify identical behavior of ICU and GLib
                    unicode backends
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dominik.roettsches at access-company.com


There are open FIXME's regarding the behavior of the GLib unicode backend
compared to to the ICU one. 

Test cases need to be created to ensure identical behavior of both for cases
mentioned in TextBreakIteratorGtk.cpp, such as:

1) FIXME: assumes no surrogate pairs

2) FIXME: UBRK_WORD case: Single multibyte characters (i.e. white space around
them), such as the euro symbol €,
are not marked as word_start & word_end as opposed to the way ICU does it. This
leads to - for example - different word selection behaviour when right
clicking.

3) FIXME: This needs closer inspection to achieve behaviour identical to the
ICU version.

When this has been done, we should be able to remove the configure-time
stability warning for the GLib unicode backend that's currently
autotools/webkit.m4.
