Missing Characters Left/Right Pointing Angle Bracket

W4RH4WK commented 5 years ago

It seems like the two angle brackets are missing (U+2329 and U+232A)

These are characters I commonly use in LaTeX math environments. It would be great if they could be added to the font.

Thanks! Mind adding a short block of your latex source for context? Shouldn't be difficult to include these.

    && \text{〈5〉 expand $l_0$ with 〈7〉} \\
    \text{〈9〉:} && f_2(l_2) \oplus r_2 &= r_0
    && \text{reduce left side} \\[-0.8em]
    \cline{1-6}
    && f_1(f_2(l_2) \oplus r_2) \oplus l_2 &= l_0 && \text{〈7〉 expand $r_0$ with 〈9〉} \\
    && f_2(l_2) \oplus r_2 &= r_0 && \text{〈9〉}
\end{align*}

I typically use them for markers. In this case each line is numbered and rather than writing line 7 I use 〈7〉. The result looks like this.

I just noticed one more thing. In Linux (Debian Testing), using Hack from the Debian repository, these characters are missing:

Using Hack in Windows, installed via the official installer. These characters are present, yet look a bit odd. Maybe there is some kind of fallback going on here, I don't know.

Thank you! You are seeing fallbacks from a different typeface in the bottom images. Whatever Debian is using as the fallback face doesn't contain the glyphs. Windows fallback seems to encode the wrong shapes for some reason. I can't explain that one...

Will try to get these drawn for you. Open to anyone if someone beats me to it.
