Anyone know why:

val t = '\u223C'  // TILDE
val a = "A" + t + "B" + t + "C"
val b = "A~B~C"
val c = "A${t}B${t}C"
println (a == b)    // false
println (b == c)    // true

?

I am getting false for both

➕ 1

A∼B∼C
A~B~C
A∼B∼C

they look same here, but different with a different font

it's false;false for me. Changing

to

val t = '\u007E'

gives true;true

hmm, now I get the same as you ggguys

Sorry, synergy keyboard 😞

The source of this question was a unit test using junit 5. In my code I concat the unicode to the String. When I use String interpolation in my assertThat(s).isEqualTo then it matches. If I now go and replace all the interpolations with a manually typed ~ then the isEqualTo fails. Could it be their implementation is flaky?

or maybe it is my ide character set

Yes I get 2 different values for '~'.toInt() and '\u223C'.toInt()
