Dear,

I am sorry to bring up \overline, \overbar, and \bar issue.

Here is a sample file and 
I attached two pdf files which were compiled using two different version of ConTeXt.

Under the LuaTeX v. 1.03, ConTeXt  ver: 2017.03.02 22:23 MKIV beta, the output overlineB.pdf is OK,
but under  the LuaTeX v. 1.04, ConTeXt  ver: 2017.05.14 19:09 MKIV beta, the output overlineA.pdf is strange.

Would you please check what is the problem?

Thank you.

Best regards,

Dalyoung

Re: \overline and \overbar

[Jeong Dal]

Dear Henri,

Thank you for your reply.
I used to use ‘\overline’ in LaTeX as shown in many texts, but it is time to change.

Thanks again.

Best regards,

Dalyoung

\overline and \overbar

[Jeong Dal]

Dear all,

In the following sample, the outputs of \overline and of \overbar are slightly different.
I used \overline in LaTeX. 
But  it takes more vertical space that cause the alignment trouble while using \overbar has no problem at all.
Is it normal behavior? 

Thank you.

Best regards,

Dalyoung

Re: \overline and \overbar

[Henri Menke]

Neither is correct in a mathematics context.  Use \bar.
