Font sizes may be adjusted (if desired together with vertical align), like this:
For a single hieroglyph in isolation, like A1, one can avoid using a canvas. This will typically be faster to render, but the appearance may differ slightly. By default, the baseline of the sign will be below the baseline of surrounding text. For high signs, it may be better to have the baseline below the baseline of surrounding text, like A1. For low signs, one may want to make the line less high, like a.
Also mnemonics may be used, like mSa. Look at res_points.js for allowable sign names and mnemonics. Again, one may vary the font size, like this: A1.
Lastly, one can use transliteration, like this: AjiyawbpfmnrlhHxXzsSqKkgtTdD. Upper case is with a caret sign like this: ^A^j^i^y^a^w^b^p^f^m^n^r^l^h^H^x^X^z^s^S^q^K^k^g^t^T^d^D.
