We have an internal report that Hebrew compact number formatting uses Latin (LTR) "K" which scrambles text if embedded in a Hebrew (RTL) message. (googleissue:171255577)
I looked at it, and the long forms are ok, but the others are not. One possibility: surround the K with RLMs.
Mark as fixVersion:38.1, meaning candidate for fix. Might do dot release, might just fix in maintenance version. Add to Known Issues on release page.
We only want RLM (200F) after the K, but not between the digits and K (since the digits are weakly L).
I am also using this to remove the random spaces in Hebrew compact currency formats per CLDR-14257.
