Issues
For Greek characters, the template works in Firefox, but not in Internet Explorer!

Note: not to be confused with {{overline}}, which produces an overline [always at cap height] over a string of characters, corresponding to the \overline{ } LaTeX command.

The {{overbar}} or {{ob}} mathematical formatting template produces a bar [at either x-height or cap height, as appropriate] over the specified single Latin or Greek character, corresponding to the \bar{ } LaTeX command, e.g.

{{math|''{{ob|a}}''{{sp|1}}''{{ob|b}}''|&}} to get the text style HTML+CSS 

a̅ b̅

or

{{math|''{{ob|a|tex}}''{{sp|1|tex}}''{{ob|b|tex}}''|$}} to get the text style LaTeX$\textstyle {{\bar {a}}{\;\;\!\!\!}{\bar {b}}}$

Examples

Bar over Latin characters

''{{ob|a}}'', ''{{ob|b}}'', ''{{ob|c}}'', ''{{ob|d}}'', ''{{ob|e}}'', ''{{ob|f}}'', ''{{ob|g}}'', ''{{ob|h}}'', ''{{ob|i}}'', ''{{ob|j}}'', ''{{ob|k}}'', ''{{ob|l}}'', ''{{ob|m}}'', ''{{ob|n}}'', ''{{ob|o}}'', ''{{ob|p}}'', ''{{ob|q}}'', ''{{ob|r}}'', ''{{ob|s}}'', ''{{ob|t}}'', ''{{ob|u}}'', ''{{ob|v}}'', ''{{ob|w}}'', ''{{ob|x}}'', ''{{ob|y}}'', ''{{ob|z}}''

yields (cap height is too low, needs ascender height)

a̅, b̅, c̅, d̅, e̅, f̅, g̅, h̅, i̅, j̅, k̅, l̅, m̅, n̅, o̅, p̅, q̅, r̅, s̅, t̅, u̅, v̅, w̅, x̅, y̅, z̅

yields the text style HTML+CSS (the dotted i and j have the bar at cap height: non dotted i and j with the bar at x-height might be better)
