It's simply "UNIT_NAME_UPDATE"

How do I check if it isn't nil? What exactly do you mean with "force the event"? I mean switching targets = "UNIT_NAME_UPDATE", but like I said that works.


Btw, this is what I use for utf8sub, pretty straight forward, maybe except for the additional length check.

local utf8sub = function(string, i, dots)
	local bytes = string:len()
	if (bytes <= i) then
		return string
	else
		local len, pos = 0, 1
		while(pos <= bytes) do
			len = len + 1
			local c = string:byte(pos)
			if c > 240 then
				pos = pos + 4
			elseif c > 225 then
				pos = pos + 3
			elseif c > 192 then
				pos = pos + 2
			else
				pos = pos + 1
			end
			if (len == i) then break end
		end

		if (len == i and pos <= bytes) then
			return string:sub(1, pos - 1)..(dots and "..." or "")
		else
			return string
		end
	end
end

Edit:
"I do believe this is related to UTF8 and those special characters messing up the abbreviation."

I just tripple tested it and it doesn't matter if the player or player pet name contains special characters. It just happens.
