How to remove emoji's from unicode string

[Stephen MacLean]

Hi Kee,

codepointOffset() doesn’t seem to work as expected, at least for me on my data, although I’m not sure why. The results are way different. I had thought it would be as simple as using that, but as per usual, nothing is!

Best,

Steve MacLean
