Ruff formatter - unicode string inside of Enum object always lowercasing characters

[DashKenny]

Hi,

I've been trying to upgrade ruff and use the formatter, so we can remove black. I have noticed this diff when using the formatter:

This enum is used to validate codes from an external API, I would rather not try and handle lowercasing that data before accessing this enum. I cannot seem to find a rule to turn off this behaviour, does this not exist or am I missing something? Nothing interesting popped out to me when running ruff format --verbose <path>

Ruff version: 0.7.0

Code snippet:

from enum import Enum


class TestEnum(Enum):
    ANGRY = '\u1F621'
    SAD = '\u1F622'

Ruff pyproject settings:

[tool.ruff.lint]
select = ["E", "F", "I", "Q", "N"]
ignore = []

[tool.ruff.lint.flake8-quotes]
inline-quotes = "single"

[tool.ruff.format]
quote-style = "single"

Command invoked:
ruff format <path> (Doesn't matter if it's only the file, or the whole repo)

hi @DashKenny

The casing of the hex-values in unicode escapes doesn't change the value at runtime:

>>> '\u1F621' == '\u1f621'
True

It's just a different way to format the same data.

Thanks for the quick reply @MichaReiser and pointing that out. That makes sense.
