Two simple ways, results will vary by font.

A. this is artificial in that it does not follow the font designers intent,
but gives clean "calculated" overlines of various forms.
1) enter the text string
2) select what needs overline
3) context menu select "Character" dialog
4) in character dialog -> Font affects tab
5) "Overlining" drop list to select desired effect

B. this uses the font designers specification, OK for a symbol but does not
work well for words or sentences.
1) enter the text string
2) advance cursor over each character and enter <l-Alt>+X
3) character will convert to its Unicode point, e.g. A -> U+0040,  a ->
U+0060
4) append the Unicode combining glyph to each character;  i.e. for COMBINING
OVERLINE U+0305, or COMBINING DOUBLE OVERLINE U+033F, or COMBINING DOUBLE
MACRON U+035e, or other from the Unicode block 0300-036F
5) merge the characters with another <l-Alt>+X at the end of each Unicode
string.
