Client side system messages in foregin langauge do not send ^L/^E/^J etc. codepage prefixes to InSim.

I know that it will impact mostly client side InSims, and within that the range of apps that would want to read system chatlog narrows it down even further, but it is minor inconvienience when creating codepage handle code from scratch, as you have to realise the bug is actually on the lfs side.
