UNOA

The most restricted EDIFACT character set, declared at the head of the interchange in the UNB.

Definition

UNOA is a value of the UNB's Syntax identifier composite (S001): element 0001 (character-set identifier) set to "UNOA", element 0002 to the syntax version number. Level A limits content to uppercase A–Z, digits 0–9, space and basic punctuation; it excludes lowercase letters. Higher levels (UNOB, UNOC = ISO 8859-1, …) widen the repertoire for accented and lowercase characters.

Origin

The syntax identifiers and their character sets are defined by ISO 9735 (UN/EDIFACT Syntax Rules), maintained by ISO/TC 154 and published in UN/CEFACT's UNTDID directory.

Example in context

UNB+UNOA:3+...' — interchange in level A syntax, version 3.
