As you have seen in the previous sections, certain special characters separate one composite in a segment from another, or separate one sub-composite from another. These special characters are known as delimiter characters.
This section describes delimiter characters in more detail, how to use escape characters to include a delimiter character as part of a composite, and how to define new HL7 delimiter characters.
HL7 Delimiter Characters
The following table lists the default delimiter characters used in HL7:
|0x0D||Marks the end of each segment.|
|~||Separates repeating fields.|
