String

base: StringFIX 4.4FIX 4.2FIX 5.0 SP2

String is a FIX datatype defined in FIX 4.4, FIX 4.2 and FIX 5.0 SP2, carried on the wire as String. 252 fields use it.

Wire format

Base type: String
Fields: 252

Free-form text. Any byte except the SOH separator is legal, so values are not trimmed or case-folded on the wire.

What the specification says

FIX 4.4

Alpha-numeric free format strings, can include any character or punctuation except the delimiter. All String fields are case-sensitive (i.e. morstatt != Morstatt).

FIX 4.2

Alpha-numeric free format strings, can include any character or punctuation except the delimiter. All String fields are case-sensitive.

FIX 5.0 SP2

Alpha-numeric free format strings, can include any character or punctuation except the delimiter. All String fields are case sensitive (i.e. morstatt != Morstatt).

Descriptions are quoted from the FIX Orchestra sources under the Apache 2.0 licence.

How @boarteam/fix handles it

@boarteam/fix keeps the value as a string; format rules are checked by validate(), which reports validate/invalid-value rather than throwing.
