Unicode (UTF-8) for overlined characters

  1. Jul 13, 2009 #1
    Hello, I have been trying to find the unicode (UTF-8) character codes for overlined upper case letters (V,L,C,M) for use in Roman numerals with the 1000-multiplier. It is basically the same letter with a bar on top of the letter.
    I also need the overlined decimal digits to display recurring decimals. I must have missed something, because theses characters appear quite basic to me.
    Many thanks in advance.

    This may not help you, but in the tex environment, you can define overbars for any characters using the \bar{} markup.

    Code (Text):

    \bar{V} ~ \bar{L} ~ \bar{C} ~ \bar{M} ~ \bar{0} ~ \bar{1} \ldots \bar{9}
     
    [tex]
    \bar{V} ~ \bar{L} ~ \bar{C} ~ \bar{M} ~ \bar{0} ~ \bar{1} \ldots \bar{9}
    [/tex]

    If you're just looking for a way to markup characters in this forum, this method can be quite handy.

    [tex]\bar{v} = \frac{x_2 - x_1}{t_2 - t_1}[/tex]

    u+305 is the combining overline, type it after a character
    0̅1̅2̅3̅4̅5̅6̅7̅8̅9̅
    V̅L̅C̅M̅

    In fact, the tex code is very useful for me too, as I need to write that as one of my steps!
    Thank you both of you for the prompt response.

    I'm glad to know it can help. I find the tex markup here to be quite useful and wish other forums supported it.
