Remove space between symbol and text when using 'expression'

Question

I want to use the function 'expression' in r to be able to add symbols as '≤' Example:

plot(1:10,1:10)
legend(3,8, c(expression(""<="test ")))

With this code there will be a space between ≤ and test, I want there to be no space: ≤test, how to accomplish this? Thanks enter image description here

does trick from here suit your needs https://stackoverflow.com/questions/43696101/r-bquote-remove-the-space-before-approximately-equal-plotmath-symbol e.g.`legend(3,5, ~phantom('')[''<= "test "], cex=3)`; suspect with multiple legend items this will take a bit of faffing about with placement / size — user20650, Jul 05 '22 at 11:14

You could use unicode symbols (\U2264 for ≤) and do it without the expression?

plot(1:10,1:10)
legend(3,8, "\U2264test") # legend(3,8, "≤test")

it doesnt work for me, see my response to the question, and an attached picture! – user11916948 Jul 05 '22 at 11:17
it works, thanks a lot! How to know this?! IS there a list of codes somewhere which is good to know about? How would it be for ≥? – user11916948 Jul 05 '22 at 11:21
