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
