I was trying to make a Lua IDE when i came across this bug with text rendering.
Keep in mind this happens much faster in real time.
Spoiler
For
probable cause
:
The negative symbol is what I'm typing, and it is likely a two byte character, however, when I backspace, I only remove one byte at a time, and this causes it to read whatever comes after the string in RAM I'm assuming.

Interesting.
I've come across things like this but it appears that TI fixed most of these memory-hacking stuff (in the upcoming version).
I can also assume you're right about direc tmemory reading and somehintg like forcing a cast to a string output, with the correspondig ascii code being some chinese chars.....
Can you see more of the memory by dumping it thourgh nspire_emu / ncubate and try to see what could match with the chinese char's ascii number ?

In case this is helpful, here's the first character that appears and keeps flashing:
http://www.fileformat.info/info/unicode/char/6d40/index.htm
The UTF-8 is 0xE6 0xB5 0x80.

I have encountered this bug before (I actually need to fix my Lua Console to support utf-8 :p), and the solution is to use TI's added string functions, uchar, ubyte and usub.
They should work just the same as their original counterparts
As for reading memory, its only a few bytes, so not so useful. But nevertheless, quite interesting

If it's any help, that's the chinese Qu character.
Don't know what it means...

This happened to me really often, when I was playing with a little text editor that I made.
I even stored chinese characters in an external string
