[Pharo-users] Get "Invalid utf8 input detected" error for a filename

Hi, If I try to execute: (FileDirectory on: '/home/jura') directoryNames it says "Invalid utf8 input detected" (UTF8TextConverter>>errorMalformedInput), because of a directory named 'Veřejné' ('ř' character is the wrong one). In the file system it is the right. FileDirectory>>primLookupEntryIn:index: returns a wrong ByteString ('Ve?ejné'). It was tested on Pharo 1.1.1 and Moose 4.3 where I am not able to use a Moose Panel tool because of the problem. Am I able to solve this problem somehow? Set-up something... Thank you in advance, Juraj
