Semantically distinct characters: Used Template:Unichar for angstrom, ohm and kelvin to bypass normalization. Previously, these were the regular unicode characters instead of the symbols. Attempting to change them by hand resulted in a null edit

Though not the intention of Unicode to encode such measuring units the repertoire includes six (6) such symbols that should not be used by authors: the characters' decompositions should be used instead.<ref>Omega, mu, Angstrom, Kelvin: {{cite web |url=http://www.unicode.org/reports/tr25/ |title=Unicode Technical Report #25 / Unicode Support for Mathematics |date=2017-05-30 |page=11 |author=Unicode Consortium}}</ref><ref name="decomp" />
* Unit symbols (6): [[Angstrom]] (Å U+{{unichar|212B|name=none}}: use U+00C5 instead), [[Ohm]] (Ω, U+{{unichar|2126|name=none}}: use U+03A9 instead), [[Kelvin]] (K U+{{unichar|212A|name=none}}: use U+004B instead), [[Fahrenheit]] (U+2109: use [[°|U+00B0]] and U+0046 instead), [[Celsius]] (U+2103: use U+00B0 and U+0043 instead), [[micro-|Micro]] Sign (µ U+00B5 µ: use U+03BC instead)
 
Unicode also designates 22 other letter-like symbols as compatibility characters.<ref name="decomp">≈ designates compatibility decomposition according to https://www.unicode.org/versions/Unicode15.0.0/ch24.pdf and is shown in code charts at https://www.unicode.org/charts/nameslist/n_2100.html</ref>
