In Sourcetree, when in Log View, on the datagrid with columns "Graph", "Description", "Commit", "Author" and "Date", commit messages and author names having unicode accented characters display as garbled text with strange characters.
But on the panel below, which displays the selected commit's full message, text appears correct.
Other applications display text correctly, only Sourcetree has this problem.
On Mac OS X 10.8.2
