text decoration with LateXSL

We wouldn't be without the apostrophe, or text with ``curly double'' quotes and `curly single' quotes---or some dashes 1--10.

\mathsf{font \tt dec\bf lar\rm ation} \quad \mbox{ and } \quad \mathsf{en\mathtt{vir}\mathbf{on}\mathrm{ment}}

The \overline command can be done with CSS border, and, depending on the browser, looks OK, except that the line is over the top line of the font, and this looks rather high on short characters. This is approach objectionable on the grounds that it constitutes conveyance of information by a presentation mechanism. Tables could also be used, but the objection is almost the same.

\overline{\overline{a}^2 + \underline{xy} + \overline{\overline{z}}}

The Unicode accent marks can be placed by CSS to render fairly well LaTeX math accents. Unfortunately, several browsers exhibit bugs related to window refresh with these. Try re-loading the document, or re-sizing the window.

Some of the AMS-TeX field symbols ℂ ℍ ℕ ℙ ℚ ℝ ℤ are available in low Unicode, but this is sort of cheating.

In the high Unicode range 1D400-1D755 (Mathematical Alphanumeric Symbols) is a full alphabet of blackboard bold style, as well as several script styles, two German blackletter, and several styles of Greek alphabets. Very few fonts support these, however. 𝜀 𝝗 𝟙 𝕰 𝔐 𝓠 𝕓

There is a Unicode character meant to put an arc over two short characters. It works, so long as it is not wrapped in HTML. So it can't be styled to go over two capital letters, or to be a little bigger to span three letters.
