I think usingpython-pi orpython_pi would be better. I think using special characters may cause garbled characters on some platform.

Hmm, what platform / filesystem are you concerned about, and what would the impact to the user on that platform be? (note in this branch we knowos.name == "posix")

A Greek letter isn't really that special. It's fully normalised Unicode (non-normalised Unicode can still be a little surprising). Looks like even FAT has supported this since around the time I was born via LFN.

See alsohttps://peps.python.org/pep-0011/#legacy-c-locale part of PEP 11

This is decidedly one of the advantages of being alive in 2024 :-)

Linux console with no framebuffer?

Console fonts without this glyph? I sometimes do math with the Diofant in the framebuffer console (yes, it has unicode support). I works well with greek letters, do some pretty-printing to display formulas. But I doubt it's able to display e.g. chinese texts an non-garbadge. (Perhaps, with other font, which I don't have...)

IIUChttps://wiki.archlinux.org/title/Linux_console says that the Linux console uses UTF-8, but we may indeed have to worry about whether the console font is missing π. The same page says the kernel built-in font can render the CP437 character set, which does have π (and dates back to the original IBM PC).

It's possible I misunderstood something, but even the case where the font is missing the glyph, is the worst thing that can happen that a user will see an unrendered glyph ifls-ing? That doesn't seem that bad, and sounds in line with the vibes of what PEP 11 describes as "won't fix". (And of course, if users report problems during prerelease we can revert)

Edit: note the CP437 stuff probably doesn't apply to U+1d70b which the PR has been updated to use. It might also have worse font support

Terminals cope with missing glyphs already (usually by rendering an ASCII?, or a dedicated replacement character).

If the active encoding is sufficiently wrong, they don't even see the raw unicode:

$ ls -d _[bd]*_build🐸  _deploy🐸$ LANG=C ls -d _[bd]*'_build'$'\360\237\220\270'  '_deploy'$'\360\237\220\270'

So yeah, as far as easter eggs go, this one is as close to genuinely harmless as they get.

From@ambv , this should use the mathematical symbol variant of 𝜋, rather than the Greek letter variant:

@hauntsaninja Let's include this, remove the NEWS, and keep the version check. Thanks!

Thanks, I've made the updates!

(Note that U+1d70b isn't NFKC normalised. I know in some cases non-normalised Unicode can cause issues in filesystems, but I think that's usually about NFC/NFD normalisation)
