Is there any convenient list of all of these characters?
Examples of such characters being:
The Hokkien (Min) 𪜶 (which is the pronoun 'them/they/theirs')
The Cantonese/Hakka/Gan 佢 (which is the pronoun 'he/him/his').
The Cantonese particle 尐 or 啲 (apparently there is some debate on what the correct character for this should be), which is frequently rendered simply (and rather bizarrely) as 'D'.
