^$Character( charsetexpr , expr1 V "IDENT" ) = expr2 V algoref
This node specifies the identification algorithm used to determine which characters in a charset are valid for use in names (i.e. is a character in the set ident).
The ident truth-value truth, of a character char using an identification algorithm ident, may be evaluated by executing the expression:
("S truth="_ident_"($ASCII(char))")
When truth is “true”, char is an ident; when truth is “false”, char is not an ident.
Note that digits are implicitly allowed in names and that for $ASCII(char) values less than 128, 65–90 and 97–122 are required to be “true” and all other values less than 128 are required to be “false”. If the identification algorithm node is undefined, or is the empty string, then it will return “false” for all $ASCII(char) greater than 127; values less than 128 will be returned as indicated.
