You have a lot yet to learn then "grasshopper" ...
Fyi - Dawb and Ntsuab are SE Asia Hmong dialects -- not Hmong scripts. Both dialect mainly use the RPA Hmong script, referred to as "Ntawv Hmoob Las Tees" in Hmong.
The other Hmong scripts throughout the world, plus a few recent inceptions include: Pollard script, Lao-Hmong script, Thai-Hmong script, Viet-Hmong script, Miao/Chinese-Hmong script, and the more
scripts are; "Flower Cloth or Paj Ntaub" script, Ntawv Uab Lag-script, an Arabic-copy Hmong script, and this bizarre one I came across/saw and being used by its group written like this mhoob, lhub, guab, plog ...

Btw - in case you did not know, there are in fact "4" Version of Phaj Hauj. Those, less than 1% worldwide, still using and preaching Phaj Hauj (Pahawh) nowadays, are solely/mainly using the First Version, because it was the only one they were taught, learned, and mastered. The 4th or last version supposedly is the easiest, most refined, and most applicable towards its intent, purpose, and usage -- according to its founder and co-founders.
Ua tsaug.
