Replace u, b and i

[kjarbr]

These are deprected in html5.

Rather use: strong for b em or mark for i

[MLatzke]

u, b, and i are all valid, as per http://www.w3.org/html/wg/drafts/html/master/text-level-semantics.html#text-level-semantics

[Sjeiti]

They might be valid, but from a semantic point of view u, b and i could be frowned upon since they do not convey a meaning but dictate a visual style. So maybe not replace them but provide an easy switch between markup style.

Has this been done yet? we are having problems with b/i/u
