some messages received from Refinitiv Real Time Optimized Websocket API have unexpected values for some fields.
"DSPLY_NMLL": "\u001b[0` \u001b[31b",
"CTBTR_1LL": "\u001b[0`<CALCS_EXPLAINED>\u001b[17` \u001b[4b"
What is this means and how can I decode this?
It is a partial field update, as mentioned in this How to retrieve page-based data using Refinitiv Tick History REST API article.
For exmple: "\u001b[0` \u001b[31b"
"\u001b[0`" represents an intra-field positioning sequence.
" \u001b[31b" represents a character repetition.
You need to apply these partial field updates to the previously retrieved data of those fields.
