[Scilab-users] Scilab 6 problem with "Prettify"

[Claus Futtrup]

Hi Samuel, et al. (I write this response just for completeness)

I loaded the Prettify code that generated an error (the default_options 
code) into my Programming Editor, which has a HEX editor function. I 
walked through all chars in the code to see if there was any peculiar 
ASCii code. There was not. The lowest ASCii char in the code was 20 
(i.e. a space) and the highest was 7A (i.e. a z). This means every byte 
in the code is (and has always been) within the normal ASCii chars.

P.S. The editor I use is TSE (The Semware Editor) Pro 4.20, see 
https://www.semware.com/ for details.

Best regards,
Claus
