This is being changed with the 6.0.0 release. The U-source for all such ideographs has been turned into a UTR #45 index, e.g., the U-source for U+FA0C is now UTC00915. What it means is that the character is a unifiable variant derived from one of the industrial (and not national) sources used by Unicode during the development of the original URO. ===== John H.
