0x25ba BLACK RIGHT-POINTING POINTER
So it seems that your environment has chosen to transcribe your chr(26) and
chr(16) into some glyphs for display, and matched those glyphs with suitable
Unicode codepoints. (Well, "suitable" if you also see a right-arrow and a
right pointing triangle; do you?)
I did with the non-printing control character, but not with '\u25ba' !
So I had to go through some contortions after some research to get my
Win7 cmd.exe and PowerShell to display the desired prompt using
'\u25ba' as the character with utf-8 encoding. My new
pythonstartup.py file (Which PYTHONSTARTUP now points to) follows:
#!/usr/bin/env python3
import os
import sys
os.system('chcp 65001') # cmd.exe and PowerShell require the code
page to be changed.
sys.ps1 = '\u25ba ' # I remembered to add the additional space.
Looks good to me. (I'm not a Windows person; the _logic_ looks good to me!)
Additionally, one must set the font for cmd.exe and PowerShell to
"Lucida Console" or the above will not work.
You may find some other fonts also work if you don't like that one.
So: I would not rely on your stuff being presented nicely if you use 16 and
26 because they are not printable to start with, and you just got lucky. If,
OTOH, you figure out some nice glyphs and their Unicode points, then many
environments will render them sensibly. Though, of course, not a pure ACII
terminal - those are rare these days though.
So let's see if this copies and pastes into a plain text Gmail and is
visible to "many environments":
Python 3.5.1 (v3.5.1:37a07cee5969, Dec 6 2015, 01:54:25) [MSC v.1900
64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
Active code page: 65001
► print("Can everyone read the prompt?")
Can everyone read the prompt?
►
It looks good to me in Gmail. Any issues? Angry users of pure ASCII
terminals? ~(:>)
I see a right pointing triangle. In green:-) But my terminals are
green-on-black.
