[whatwg] size attribute

All user agents should take the effective language into account for the
purpose of evaluating the average character width.  This is not how the
browsers currently behave.  However, since the rendering section is
non-normative, describing the right behavior does not break the Web.  It is
irrelevant what all the browsers currently do, unless a vendor (or anybody
else) stands up and convinces us that this postulated behavior is wrong or
impractical.

You take the equivalence between characters and glyphs for obvious and
granted because you are English; however, for a significant part of the
humanity this is simply untrue.  Please reconsider.

Cheers,
Chris
