"Jiu-Jitsu" and "Jiu-Jutsu" were THE standard romanizations of the term when it was first romanized in the late 19th Century and early 20th. Look at Barton-Wright, Lanius, Liederman, Gotch, Hackenschmit, Fox's, etc., all from the late 19th and early 20th and all use "Jui-Jitsu." IMS, even the English manuals written by Japanese practitioners (Tani, iirc) have this spelling in the originals. This is a direct result of what linguists at the time were saying and it entered common usage, there to remain for more than a Cetury and still going strong.and the only acknowledged use of this common mis-spelling is Brazilian Jiu-Jitsu (who actually manage to get both characters wrong...).
