  • One participant expresses appreciation for the TeX code, indicating its usefulness for their own work.
  • Another participant shares their positive experience with the TeX markup, wishing for broader support in other forums.

Areas of Agreement / Disagreement

Participants generally agree on the utility of the TeX markup for overlining characters, but there is no consensus on the availability of specific Unicode characters for this purpose.

Contextual Notes

Some limitations may exist regarding the completeness of available Unicode characters for overlined letters and digits, as well as the context in which the TeX markup can be applied.

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

<br /> \bar{V} ~ \bar{L} ~ \bar{C} ~ \bar{M} ~ \bar{0} ~ \bar{1} \ldots \bar{9}<br />

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.
