A short example for error reproduction would be a perfect help.
Or can you see from where the getAbsoluteCodePointOffset got called from
or with what parameters?
If nothing else works, you can use tango.util.log.Trace to hexdump the
arguments with Trace.memory.
So the question is, is getAbsoluteCodePointOffset wrong, or is it called
with invalid args.

Seems exception on ApplicationWindow.setStatus(longerUtf8Str); dwt split longerUtf8str to invalid Chinese characters I guess. -- yidabu <yidabu.spam@gmail.com> http://www.dsource.org/projects/dwin D 语言-中文(D Chinese): http://www.d-programming-language-china.org/ http://bbs.d-programming-language-china.org/ http://dwin.d-programming-language-china.org/ http://scite4d.d-programming-language-china.org/ |

With this few information it is hard to help.
Can you give me an example of the input string, so i can try to find out what is the problem?
for example put this at the start of getRelativeCodePointOffset:
Trace.formatln( "str={}, startIndex={}, searchRelCp={}", str,
startIndex, searchRelCp );
Trace.memory( str );
and post the output.
Also using the stacktrace enabled tango lib from team0xf can help.
