As far as I know, for one glyth (ex.: 御) there many variant forms.
Some sources list 䘖䘘禦 as variants, others say that all of the glyths in string 御䘖䘘䢩禦衘馭𠉳𠨙𡕺𢓦𢕜𢖋𤀝𧗨𧗪𨝈 are variants of 御.
Is there a reliable source where I can find all (or most of) the variants for a given glyth. I need only CHARS, that is those you can type with in modern PC.
