rich.table prints unicode when I want ascii

Question

I am trying to print MAC address using python rich library. Below is code. The ":cd" in the MAC address get converted to an actual CD disk emoji. How to prevent that from happening?

from rich.console import Console
from rich.table import Table

table = Table(safe_box=True)
table.add_column("MAC address")
table.add_row("08:00:27:cd:af:88")
console = Console()
console.print(table)

Output:

┏━━━━━━━━━━━━━━━━━┓
┃ MAC address     ┃
┡━━━━━━━━━━━━━━━━━┩
│ 08:00:27af:88 │
└─────────────────┘

I tried using safe_box=True option to not print Unicode but that did not work. I want the final output to look like

┏━━━━━━━━━━━━━--━━━━┓
┃ MAC address       ┃
┡━━━━━━━━━━━━━━━--━━┩
│ 08:00:27:cd:af:88 │
└───────────--──────┘

The documentation describes this. You use backslash to escape characters that would otherwise be recognized.

table.add_row("08:00:27\\:cd:af:88")

If you have a string, do

s = s.replace(':cd','\\:cd')

I looked at the full emoji list in the source code. There are two possible paths.

First, they look for the Unicode "zero-width joiner" as a way to interrupt the emoji search. So, you could do:

s = s.replace(':cd',':\u200dcd')

Second, "cd" is, in fact, the only two-letter emoji code in their list that is also a hex number. So, you can add this at the top, and this also works:

from rich._emoji_codes import EMOJI
del EMOJI["cd"]

I've tested both of these. What a very strange problem.

":cd" is just one example. There could be other unicode characters in a MAC address which we cannot predict. Do we look for all of them each time? Is there a more generic solution? – Akhil Kadway Dec 03 '22 at 07:26
Sure, you can escape every colon. `s.replace(':','\\:')` – Tim Roberts Dec 03 '22 at 07:59
It did not work for me. I tried table.add_row('08:00:27\\:cd:af:88'), still prints the CD – Akhil Kadway Dec 03 '22 at 08:18
I see. That's contrary to their documentation. I'll look at the source. – Tim Roberts Dec 03 '22 at 18:42
Its a weird issue indeed. I which there would be some know to just disable unicode. Anyways I found some more emoji codes which could also be hex numbers. "ab": "", "a": "", "b": "", – Akhil Kadway Dec 05 '22 at 05:57
You do see how to extend my code to include those, right? – Tim Roberts Dec 05 '22 at 18:50
