# Unicode (UTF-8) for overlined characters

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.

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}

$$\bar{V} ~ \bar{L} ~ \bar{C} ~ \bar{M} ~ \bar{0} ~ \bar{1} \ldots \bar{9}$$

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

$$\bar{v} = \frac{x_2 - x_1}{t_2 - t_1}$$

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.
