getObjectByPath crashes when path contains certain accented characters

[e-voci]

Hello.
Invoking getObjectByPath silently crashes the application (no exception is raised, the application simply dies) when path contains certain accented characters.
One of these I've identified is the "č" (U+010D, č, c4 8d, č, č, LATIN SMALL LETTER C WITH CARON).
My test application is a console command copying files from the local filesystem to an Alfresco 4.2 repository.
How to reproduce: invoke
getObjectByPath(parent['cmis:path']+'/'+filename).ok(function(folder){
with filename = "pače.txt"
