Normalize backlink slug comparison

[jacobbudin]

Fixes #87

The issue demonstrated in jrekier/mind-garden is that while the strings represent the same characters, they are not byte identical. (See "proof" below.) Calling String.prototype.normalize() before the comparison returns the expected match.

$ echo "Poincaré equation" | hexdump -C

@jrekier Does this solve your issue (#87)?

[binyamin]

@jacobbudin Thanks for your work. I extracted the backlinks logic to a plugin (binyamin/eleventy-plugin-backlinks). If you want to patch it there too, go ahead.

@binyamin Sure: https://github.com/binyamin/eleventy-plugin-backlinks/pull/2. Hope this helps.

@binyamin looks like it :) Thanks @jacobbudin, I'd never have thought of that.
