/**
* Scilab codes for known characters
* In Scilab, chars are first converted as integers (positives and some
* negatives) and we have :
*
* code | 0 1 .... 9 | 10 11 ... 35 | 36 37 38 39 | 40
* -----+-------------+----------------+----------------+------
* char | 0 1 .... 9 | a b ... z | _ # ! $ | blank
* ============================================================
* char | | A B ... Z | ? | tab
* -------------------+----------------+----------------+------
* code | |-10 -11 ... -35 | -38 ! -40
*
* In fact (for the mapping code -> char), code = -1
* to -9 correspond also to chars 1 to 9 and code = -36,-37,-39
* to the char 0
*
* So if c is a scilab coded char then :
*
* abs(c) <= 9 => c is a digit
* abs(c) < 40 => c is an alphanum Scilab char (which
* comprise _ but also # ! $ ?). Moreover
* Scilab names may begin with %
* abs(c) == 40 => c is a blank "like" (blank or tab) char
* The upper-case characters and some equivalents are coded by the lower-case code with a sign
* change.
