Due to convention a script "l" - $$\ell$$ (LaTeX \ell) is used to represent a certain quantity in something I'm working on. I'm unable to figure out how to use it in R. It's not included in the list on ?plotmath. 

Can anyone tell me how to use it?  Its unicode is U+2113. This page has a list of various encodings of it: http://www.fileformat.info/info/unicode/char/2113/encoding.htm.  Is there a way to include it by using one of these encodings somehow?
