RMarkdown changes a good URL containing "-" into an error

Problem

Wikipedia has an article on Gaussian quadrature, which I can link to in RMarkdown. It also has an article on Gauss-Hermite quadrature. After I knit this to a PDF, I can link to the first, but the second fails.

Specifically, in the second case, I ask to go to:

Instead I get

https://en.wikipedia.org/wiki/Gauss/T1/textendash_Hermite_quadrature

This occurs with "output: pdf_document" but NOT with "output: html_document".

What do you suggest?

Thanks,
