String contains weird characters and client drops after time with no activity

[nojaf]

Hello,

I've experienced some strange problems when the client sends messages to the server.
Extra characters were included in the string and I have no idea how this was possible.
For example:
Client sends: "3::3#Bernardus trippel#22;7#Cola #12;5#Hommelbier#19;8#Ice tea #14;2#Kriek#12;1#Primus#12;4#Sint bernardus Prior#18;6#Tongerlo#17;9#Water#13;"
but server receives:
"3::3#Bernardus trippel#22;7#Cola #12;5#Hommelbier#19;8#Ice tea #14;2#Kriek#12;1#Primus#12;4#Sint bernarȁ��ȁ��dus Prior#18;6#Tongerlo#17;9#Water#13;"

I'm using the latest version of Chrome and it's hard to reproduce this error.
Did I miss some setting here?

Another problem I have is that when a client connects and there is no communication for like 5 minutes, the connection is droppped. How is this possible? Or am I missing another setting?

But besides that is the framework really great so yeah thanks!
