plsesc: Set the escape character for text strings
    Set the escape character for text strings.  From C (in contrast to
    fortran, see plsescfortran) you pass
    esc as a character.
    Only selected characters are allowed to prevent the user from shooting
    himself in the foot (For example, a "\" isn't allowed since it conflicts with C's use
    of backslash as a character escape).  Here are the allowed escape
characters and their corresponding decimal ASCII values:
"!", ASCII 33
"#", ASCII 35
"$", ASCII 36
"%", ASCII 37
"&", ASCII 38
"*", ASCII 42
"@", ASCII 64
"^", ASCII 94
"~", ASCII 126
