Display Greek small letter mu (#14426)...

Display Greek small letter mu (#14426) `%time foo()` output is often copied into code comments to explain performance improvements. The `\xb5` Latin Extended micro sign and the `\u03bc` Greek small letter mu have different codes but often look identical. Output mu to align with: * [The International System of Units (SI) brochure]( https://www.bipm.org/documents/20126/41483022/SI-Brochure-9-EN.pdf ), such as Table 7 SI prefixes * NFKC normalized [Python code](https://peps.python.org/pep-3131/ ) and [domain names](https://unicode.org/reports/tr36/). For example: ```sh python -c 'print("""class C: \xb5=1 print(hex(ord(dir(C)[-1])))""")' | tee /dev/fd/2 | python - ``` ```python class C: µ=1 print(hex(ord(dir(C)[-1]))) ``` `0x3bc` * Section 2.5 Duplicated Characters of [Unicode Technical Report 25]( https://www.unicode.org/reports/tr25/) > ...U+03BC μ is the preferred character in a Unicode context. * Ruff confusable mapping [updates]( https://github.com/astral-sh/ruff/pull/4430/files ), currently in the "preview" stage Add a unit test for UTF-8 display and https://bugs.launchpad.net/ipython/+bug/348466 ASCII fallback.
