Efficiently replace all accented characters in a string?
...
What I'm trying to do is make the sorting of the jQuery tablesorter plugin work correctly for table data in German. The plugin can take an user-defined function to extract the string to sort on, which is what I have to do or the resulting sort order will be wrong.
