EncodedSecurityListDesc (FIX tag 1469)
EncodedSecurityListDesc (tag 1469) is a data field defined in FIX 5.0 SP2. It appears in 2 message types, always optionally. It is length-prefixed — tag 1468 carries the byte count, so the value may contain the SOH separator without breaking the message.
At a glance
What the specification says
Encoded (non-ASCII characters) representation of the SecurityListDesc(1467) field in the encoded format specified via the MessageEncoding(347) field. If used, the ASCII (English) representation should also be specified in the SecurityListDesc(1467) field.
Descriptions are quoted from the FIX Orchestra sources under the Apache 2.0 licence.

| 10 | CheckSum | 173 |
Shown with | separators for readability. On the wire FIX uses SOH (0x01), an invisible control byte — and because BodyLength and CheckSum are computed over the actual bytes, the two forms have different checksums. Both are valid and both decode here.

Where tag 1469 appears
Requiredness is a property of the message, not of the field: the same tag can be optional in one message and conditionally required in another.
| Message | MsgType | Requiredness | Where in the message |
|---|---|---|---|
| SecurityList | y | Optional | directly on the message body |
| SecurityListUpdateReport | BK | Optional | directly on the message body |
Wire format
Raw bytes, length-prefixed by a partner field. The value may legally contain the SOH separator, which is why the length matters. @boarteam/fix reads the partner length field first and takes exactly that many bytes, so an embedded separator does not truncate the 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.
