Greeh phi symbol U+03D5 missing from TTF format

[mdealencar]

From the issue #565, it seems like that there is a glyph for U+03D5 in Iosevka. But I'm using the ttf fonts and this symbol is not being found (some programs replace it with another fonts' glyph, others with a placeholder).

• Your font version: 3.6.2
• Your font variant:
• Your operating system (name and version): Debian Linux testing
• Your application using Iosevka: terminal, jupyter-lab, xelatex

Tested the latest build and the glyph is there. Could you please perform a clean uninstall, clear font cache, and reinstall?

There is nothing wrong at mine, too.

I think this may help:
$ sudo fc-cache -r
$ sudo shutdown -r 0

Thanks for the reply. I found the problem with another font that also has the glyph. It must be some problem in my system.

The other Greek letters work fine (such as the phi's at U+03C6 φ and U+03A6 Φ). As a workaround, I' using the phi at U+0278 ɸ.

I don't understand enough about the handling of unicode on Linux to figure this out.

You probably have a special confutation stuffed in fontconfig to override the font for a specific character or range. Sometimes misguided package maintainers think it's cute to package things like this with fonts installation. Some Magic Greek Font™ that you installed packages for may have thought it in your best interest to hijack this symbol.

What Linux distro are you using? Edit: I see you mentioned this was Debian. I would first do an audit of what other fonts you've installed that cover Greek. Also scan your /etc/fonts/conf.d folder for any config files that look suspicious. The conf files in there can do different things some of which are good, but it's possible to do bad things like this too.

Emoji fonts and symbol packages are notorious for doing stuff like this.

Closing as external.

I apologize for the bogus bug report.

I got it sorted out now: when I was looking for the phi symbol ϕ (instead of the φ U+03C6 I was getting with the <dead_greek>+<f> combination), I used "\phi" with MathJax to get the desired phi shape (𝜙) and copy-pasted it. Later, when I started having problems, I found out about U+03D5 (ϕ) and I wrongly assumed I was using it, when 𝜙 is actually code U+1D719 (Mathematical Italic Phi Symbol) in the Mathematical Alphanumeric Symbols block.

I wish I knew a better way of converting from the character to its code, but I will leave here what finally got me on the right track:
In ipython (or jupyter):

In [1]: hex(ord('𝜙'))
Out[1]: '0x1d719'

@mdealencar In vim you cat get the code for the character under the cursor with ga. Some plugins expand the information given with details from UCD or elsewhere. Many other editors have similar features (or plugins), I just don't know them off the top of my head. There are also quite a few tools online to do such lookups. Here is one
