Wire format

Base type
char
Fields
71

A single character. Most char fields are enumerated, so the value is one of a fixed set rather than arbitrary text.

What the specification says

FIX 4.4

Single character value, can include any alphanumeric character or punctuation except the delimiter. All char fields are case sensitive (i.e. m != M).

FIX 4.2

Single character value, can include any alphanumeric character or punctuation except the delimiter. All char fields are case sensitive

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 and, for enumerated fields, reports validate/value-not-in-enum when it is not a defined value.

Decode this in your own code

The same engine that produced the decoded example above is an Apache-2.0 npm package with zero runtime dependencies. It runs in Node and in the browser, and parse() returns problems as data instead of throwing.
