If you are missing output after someone's name in the chat, for example, if instead of seeing:
[RUF] Hawkinsthis is a test
you just see:
[RUF] Hawkins
Then the 'unprintable' character seperator (0x15) may be causing a display issue depending on what editor you are using. If you can't see it within the parser itself, then I can't really say without seeing a copy of your log file (or a portion of it that contains the glitch.)
I noticed that you are from the UK, so it could be possible that you are using a different character set than we are here in the States. If thats the case, I may need to make an update :)
