There's a problem in the specs here. The href attribute is required to be a
legal URI Reference, and to ensure this, the XSLT serialization spec
requires that the "_" is encoded as %C3%9F. But no similar encoding is
applied to the name or id attribute of the anchor (and it would be illegal,
at least in XHTML, because % is not allowed in an NCName); and some browsers
at least won't match a %C3%9F in the fragment identifier of the href URI to
a "_" in the name attribute.

I think what this means in practice is that it's unsafe to use non-ASCII
characters in the names of HTML anchors.
