In the SBL Greek NT of Eph 1:1 there are upper square brackets around Χριστόu Ἰησοῦ.
It seems the square brackets come from Logos Symbol Unicode, a font that I sometimes have installed and sometimes not.
If the font is not installed then Logos5 shows nothing, or square boxes.
When imported into Word2010 these brackets can appear or not, depending on the weather.
I normally use SBL BibLit for both Hebrew and Greek. Sometimes these fonts render the upper square brackets and sometimes they don't.
Please correct me, here, but why not use the unicode characters within SBL BibLit to render the upper square fonts?
Here I have used 231C and 231D
