[CAS] Inconsistency with commands.

[parisse]

In CAS, you should use lowercase. char/asc is working in ASCII (8 bits char) extended to UTF8, while HOME is using UTF16 (16 bits char). For example
asc("a") returns a list of 1 integer
asc("é") returns a list of 2 integers
and char does the reverse.
Which means that the sqrt symbol is coded inside CAS with UTF8 corresponding to UTF16=8370, that is with 3 integers 226, 136, 154, that you get with asc.
