19.5Texas Standard Electronic Transactions Acceptable Extended Character Set

19.5.1Alphanumeric Field(s)

(1)For use on an alphanumeric field, Texas Standard Electronic Transaction (TX SET) recognizes all characters within the basic character set. Further clarification and additional character set validations are available within each Texas SET Implementation Guide that is located on the ERCOT website.Within the extended character set, TX SET recognizes all character sets except all select language characters found in Section (4) of American National Standards Institute Accredited Standards Committee X12 (ANSI ASC X12) standards application. Segment/data element gray box guidelines for alphanumeric fields take priority over ANSI ASC X12 standards where the TX SET guidelines further limit acceptable values for a segment/data element. TX SET guidelines cannot extend the acceptable values to characters that are not allowed by ANSI ASC X12 standards for a segment/data element.
