Therre are a lot of Greek letters/symbols in most MS ttf fonts.
However some symbols are not anywhere.

Has anyone experience with a font that has symbols such as x-bar (x with an overscore) used for the mean of a sample, p-hat, the letter p with the symbol that appears over the 6 on the keyboard over the p?

Food for thought: http://www.personal.psu.edu/ejp10/blogs/gotunicode/2010/03/dealing-with-x-bar-x-and-p-hat.html and http://user.services.openoffice.org/en/forum/viewtopic.php?f=7&t=45660

Thank you much for your link and the code.

I'm still wondering about the xbar and p-hat characters. Are there any 'statistics' fonts out there with such symbols. Neither link 'solves' this issue.
