I am looking for two news symbols that are yet not available
in The Comprehensive LaTeX Symbols List in CTAN.
( I need to use them in a document with mathpazo font
and using pdfLaTeX.)

(i) An upper semicircle
so that a macro like \semi{X} places a semicircle on top
of the letter "X"  (the symbol \frown is not what I am
looking for, but a half circle).

(ii) same as above, with the central dot includec.

Any help will be appreciated.
