This is a sequence of two Unicode characters, viz.
U+0078 LATIN SMALL LETTER X
U+0305 COMBINING OVERLINE
Incidentally, the bar (rather than x-bar) signifies the mean; the bar
could be applied to any name indicating the mean of all and any values
having that name. In this respect, the combining overline mimicks the
mathematical formalism better than any x-bar character would.
Whether your software is capable of rendering the U+0078 U+0305 sequence
correctly, is another question. Ask your vendor for a decent Unicode (aka
ISO level 3) implementation.
