A section title with accented character leads to MD051 but it should be valid.

# Title with à accented character

[Link](#title-with-à-accented-character)

3 - MD051 / link-fragments Link fragments should be valid [Context: "[Link](#title-with-à-accented-character)"]

GitHub's implementation translates accented characters into their URI encoded form - in this case "%C3%A0". (You can confirm this by looking at what's generated by the little anchor tag for that link on GitHub.) If you use that expanded form for your link, no warning is generated. This rule looks for that canonical form to be used and is behaving correctly here.
