That's correct. This is the example of stop-bit encoding that I have referred to in the past. It's actually the FAST (FIX Adapted for STreaming) protocol, and not the standard FIX format.

I have heard of other places using this also. This is modern, current, non-legacy usage. This is the length encoding where the most-significant bit of a byte is used to determine whether there are more ASCII characters or not. The last byte will have the most-significant bit of 1, prior bytes most-significant bit of 0. Minimum length in this length kind is 1. It seems we are missing this lengthKind, which applies only to text in the ASCII/US-ASCII encoding.
