* src/support/tempname.C (tempName): Return FileName in utf8 encoding. * src/lyxsocket.[Ch] (LyXServerSocket::LyXServerSocket): Use FileName instead of string and set the env var LYXSOCKET in the filesystem encoding as this is what the client expects. * src/support/socktools.[Ch] (socktools::listen): Convert to FileName and use the filesystem encoding for the file names stored in the sockaddr_un struct. * src/client/client.C (socktools::connect): Convert to FileName and use the filesystem encoding for the file names stored in the sockaddr_un struct. (LyXDataSocket::LyXDataSocket, main): Convert to FileName. * src/lyx_main.C (LyX::exec): Use FileName instead of string in socket code. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@17749 a592a061-630c-0410-9148-cb99ea01b6c8
