26,ThreadScope shows garbled characters when using Unicode characters in user event,shelarcy,,"Debug.Trace.traceEventIO output Unicode characters by UTF-8 String.

 * http://www.haskell.org/ghc/docs/7.4.1/html/libraries/base-4.5.0.0/Debug-Trace.html#v:traceEventIO

""ghc-events show"" can show output Unicode characters' user event correctly.

{{{
import Debug.Trace
main = do
    traceEventIO ""テスト""
    putStrLn ""test""
}}}

{{{
$ ghc -O2 -threaded -eventlog Test.hs

Linking Test.exe ...

$ .\Test.exe +RTS -l
""test""
$ ghc-events show Test.eventlog > test.log

But ThreadScope can't show Unicode characters' user event correctly. ThreadScope shows garbled characters.

This is bad. Unicode character is useful to find user event for me.
