Re: [clreq] Fullwidth is not equivalent to em (#511)

As conventionally em differs from what we intend to mean in this document, and this document is not just oriented to Chinese users, I think there is a need to explain “em”, or replace it by other words.

A CSS unit in [CSS Values and Units Module Level 4](https://www.w3.org/TR/css-values-4/#ic) is worth mentioning here, which may help.

> ic

> Represents the typical [advance measure](https://www.w3.org/TR/css-values-4/#length-advance-measure) of CJK letters, and measured as the used advance measure of the “水” (CJK water ideograph, U+6C34) glyph found in the font used to render it.
