@tancredi, would love a review on this one-line fix.

Currently, fantasticon doesn't correctly support code points greater than 0xFFFF, because String.prototype.charCodeAt() only supports UTF-16 code points, whereas String.prototype.codePointAt supports all Unicode code points. This is necessary to reach the private use areas in the ranges U+F0000..U+FFFFD and U+100000..U+10FFFD, which is necessary when creating icon fonts with more than 6400 glyphs.
