App crashes on non-printable characters

[bastixx]

I have found an possible error in the application. It seems to crash when it encounters a non printable character.

One of the bots on twitch "Stay_Hydrated_Bot" uses Control Characters in its message, which are non-printable. This crashes the app. Attached is the output_log.txt. I have removed all channel identifying information, as this is not my channel.

Thanks! Seems to be an internal Unity issue. All I could do here is sanitize the text, but I'll see about doing so.

Any idea exactly what the characters are? Google doesn't seem to accept
or
(everything seems confused by these) :0

Yea, they seem to be Control Characters. In this case specifically the SOH character, indicating an header. This is the only CC I have seen so far.

I have no clue why this bot sends this character, or why Twitch even passes these on, as they serve no purpose on twitch as far as i know..

Thanks! I realize now that I should have just checked them against any of the readily available ASCII converters. Hindsight and all that :). I should be able to sanitize them easily.

Okay, good! Hoping that this will fix the crashes then :)

Could you try this new build? This one should strip all characters except Alphanumeric and the following list

{ ' ', '!', '"', '#', '$',
  '%', '&', '\'', '(', ')',
  '+', ',', '-', '.', '/',
  ':', ';', '=', '>', '?',
  '@', '[', '\\', ']', '^',
  '_', '`', '{', '|', '}', '~'};

This should be every character from 00100000 to 00111110

Btw, unfortunately I was unable to reproduce the issue. The exact text causing the issue

ACTION @ahyBottle You've been live for just over 1 hour. By this point in your broadcast you should have consumed at least 4oz (120mL) of water to maintain optimum hydration.

does not cause any errors for me in v1.0.7.4-test1. I also could not reproduce the issue with any of the control characters which I could reproduce in Twitch chat.

However, hopefully stripping the characters fixes the issue for you anyway.

Hmm, weird.. But I asked the streamer to try out this new build, so we will know if this resolved the issue after his next VR stream :) I will report back if we encounter any issues!
