Hyphens aren't detected in Preview on OS X

This also occurs with hyphens in documents generated by Google Docs, but for example "higher-numbered" in the PDF reference works fine, so it could be something to do with the font we're using.

Try an annotated file in another PDF reader to see if this is across the board.

This is unfortunately across the board. Perhaps it's easiest to try using another font...
