I need to type a right triangle symbol, whose unicode is U+22BF or U+25FF, see


What I get in the template I used is


I don't want to change to utf8x.

The engine I use is pdflatex.

I can't figure out how to make it work. Is there a way to type the unicode code to obtain the unicode symbol in output?

  • Do you need the symbol in math and scalable in superscripts/subscripts? – egreg Sep 28 '15 at 21:06

Picture mode to the rescue:




x \lowerrighttriangle{} y
