The reason why I'm saying this is because we can't be sure that the
font being used at the target would include glyphs for those alternate
curly braces, and when it doesn't it would typically cause ugly 
replacement glyphs (usually a square outline) to be rendered.


But to set the record straight: we're not talking about a degradation
to current here. Right now this doesn't work at all (text inside 
curly braces being invisible)
