Edit: This is not a duplicate of that question, because this does not work, while that was fixed. So this is a new issue.


The character ² is not a valid search character. On EE.SE, one common term is I2C, sometimes (correctly) spelled as I²C (IIC or I-squared-C). A search for I²C does not throw an error, nor does it return anything with I²C, instead it results in questions and answers including IC, an unrelated term. And the automatic url recognition does not work when ² is in the url.

For example I2C bit banging²c-bit-banging

Notice how it hyperlinks I²C bit banging to https://electronics.stackexchange.com/questions/203076/i, while duping ²c-bit-banging?

Notably, ² is valid in an url, so it will bring up the correct question if copied and pasted, or hyperlinked, but not in the search or url parsing.

Can this be fixed by the code review team? This is a valid Unicode utf-8 character Superscript 2 hex 0x00B2

If anything, can a search for, and results for, ² be mapped to 2?

  • @ᔕᖺᘎᕊ since Unicode is supposed to work, wouldn't this be a bug and not a feature-request? – cde Nov 29 '15 at 1:33
  • yes, it is a bug. I removed the codereview-se tag because it stood out as being completely irrelevant! I didn't really look at the other tags. But I see @Monica has edited it :) – ᔕᖺᘎᕊ Nov 29 '15 at 10:43
