Expected behavior

0x03bc Greek small letter mu displayed

Characters which look the same but have different underlying codes (homographs) are problematic. The abbreviation for microvolts is best represented as μV, using the 0x03bc Greek small letter mu, instead of the 0x00b5 Latin Extended micro sign. This aligns with:

• The International System of Units (SI) brochure
• NFKC normalized Python code and domain names
• Section 2.5 Duplicated Characters of Unicode Technical Report 25
• Bokeh's histogram example

Observed behavior

0x00b5 Latin Extended micro sign displayed
