It is indeed a real world problem, but the problem is in the font, and 
the font is what needs to be fixed. Fixing the non-broken parts like 
Unicode, HTML, or DOM just locks in the brokenness and assures that 
nothing will ever work. If we leave HTML, Unicode, and DOM alone (on 
this issue) then eventually the fonts will get fixed or replaced, at 
least within the limited community where this matters.
