I have a strange problem using ± and ∓ Unicode symbols as variables when
placed at the front of equation. Although they seem not to be defined in
Main, they behave differently from e.g. α (but e.g. 2*± does work). See
below. Any suggestions?

Couldn't find ±
Perhaps you meant *, α, !, $, %, &, +, -, /, :, <, >, I, \, ^, e, |, ~, ×,
÷, γ or π
