Make text overline like underlining

[Alan]

Is there a way of overline text (to make a square root equation) like underlining text can be done?

[admin]

There is no standard way to do so. But you could insert the "overline" character (Unicode number 175), and format it with "compressed" character spacing. Please see attached sample document file.

Thank you, the suggestion worked very well. Is there a way to translate this for an ePub, so the overline shows in an ePub?

Hi Alan,
Overscoring text is rather cumbersome to achieve in HTML. The problem is the same in EPUB code which is basically XHTML code.
The most practical solution is to create overscored text in Atlantis as Admin indicated, make an appropriate screen capture of it, and overwrite the original text with the screen capture. The picture with overscored text will be saved to EPUB, and will display correctly in all EPUB readers.

Note that there is an alternative way to create overscored text in Atlantis using a 2x1 table with appropriate borders and the square root Unicode character “√” (√). Typing “Alt+8730” in Atlantis will produce the square root character. Attached “Overscore.rtf” illustrates this possibility.

Alternatively again, you could use the Atlantis tweak_epub utility, and edit the EPUB code produced by Atlantis, using the HTML code illustrated in attached “Square root.htm” ("Square root.zip"). Note that a much better result can be achieved with complex HTML and CSS code: you’ll find an illustration of this at Solve square-root equations (basic), for example.

HTH.
Cheers,
Robert

Thanks for the suggestions Robert. This is more complicated than I want to get into as this would only be for my use on my Kobo Glo eReader, this would have been the icing on the cake.
