Approximately Equal Symbols
Several symbols look like approximate equality, but they are not interchangeable in every field.

01
Start with meaning, not appearance
Choose ≈ for general numerical approximation. Use ≃ for an asymptotic or related convention and ≅ for congruence or isomorphism when your field defines it that way.
02
Name and code are stable
Unicode gives each character a distinct name and code point. Those identifiers are the safest way to distinguish similar glyphs.
