Last time I looked, some glyphs were missing from Unicode. Looking this 
time, the box-drawing characters in the U+2500 range seem to contain 
most things.

I do not think that the control codes (colour selection, ctrl-r, ctrl-R 
to switch reverse mode on/off, ctrl-n, ctrl-N to switch character sets, 
etc) can be converted to Unicode and back in a two-way fashion.

If the files are straight text, you could convert it to ASCII using the 
tr command. tr is not compatible with multi-byte character encodings, 

Last but not least, speaking of PETSCII can be ambiguous. It could be 
the lower-case/upper-case character set, or the upper-case/graphics, or 
screen codes.
