Here's mine. The first unknown allows a second item attribute to be attached to the item via the first item unknown flag in the Patcher (potentially to allow more combinations) and the second flag attaches a R/S/M by ability ID. It automatically adds x100 so, for example, you would set the secondary flag as E2 to allow Short Charge with the Item. This asm is not as heavily tested as my other ones but I tested it again today and couldn't find anything. Please let me know if you come across an issue so I can fix it.
Edit: I also have another version of this one that uses the Kanji space you mentioned to allow R/S/M to have an attribute attached to it (IE blank support gets Fire Absorb/Water Weak through attribute) but I haven't finished that one completely since I'd hate to use that extra space just to throw a table on it. If you're interested, I could fix the display issue (functionally it works) and toss it in with this.
Edit 2: Busted
