207.1 Information exchange package format
An exchange package shall contain one or more logical records pertaining to a single subject.
The data in every record shall always be recorded in variable length elements using the 7-bit
American National Standard Code for Information Interchange (ASCII) as described in ANSI
X3.4-1986 and Annex A. For purposes of compatibility, the eighth (leftmost) bit shall contain a
value of zero.
For data interchange between non-English-speaking agencies, character sets other than 7-bit
ASCII may be used in non-image elements. UTF-8 is the preferred method of storing textual data
that cannot be represented as 7-bit ASCII. This method supports international character sets for
all user-defined elements in all record types. The mechanism to change character sets is
described in Section 208.2.3, International Character Sets. By definition, UTF-8 and other
international character exchange methods are not applicable to record Type 1.
