Hello,
This doesn't apply for french version, special Char like é, è, ê or î, ï, does not appear. (Maybe a kind of "NumStrings 5256 to NumStrings 5353" 's problem in the String folder. )
When i've seen that the update was for English-version only, it was too late.
( or I was too excited for read this : "Please note that this update is ENGLISH ONLY. The French and German versions are still undergoing testing and will be made available at a later date." )
It seems that Impulse loves "clean" menu like just one button to dash on whithout warning or thing like that.
I know, I know ... It was all my fault. 
(Sorry for my English.)
edit : Finally, I'd took my French.str from my 1.05, I've searched for all char like é è à î ï etc ... with my notepad++ & I replace all of them with more standard char on each research. It works while i'll waiting for the real localized fix. 
Ps : Thanks to Transgalagtique's crew who had let appears some comments about this problem on beta 1.09 translation
