In Chinese I guess you see the various "kana" forms. In Japanese, they input the "gojuonhyo" or alphabet and see various Kanji. At least that was the last word processor that I saw that worked in Japanese. To my Japanese friends, the term "word processor" brought to their mind a blendor filled with characters as the concept is not the same to them as it is (or was) to us.
As for Metol vs pAP, I agree, but since pAP is similar to Metol in activity to Sulfite, (IIRC) then the concentrates of the two Rodinal experiments using Metol vs pAP should keep in a similar manner. This is what is bothering me about the keeping of "Metonal".
