'toString().contains()' method unable to detect '˚' (degree symbol) inside a CharSequence

Question

I have a CharSequence which contains two ˚ (degree) symbol inside it.

I have written an if statement which detects what's inside this CharSequence like this:

CharSequence name = "27°46'29.6"N 77°19'05.9"E";

if (name.toString().contains("˚") {
     Log.d("log", "˚ detected");
} else {
     Log.d("log", "˚ not detected");
}

The problem is that here ˚ detected is supposed to be printed out by the log statements, but what is getting printed out is ˚ not detected.

Why the ˚ is not getting detected?

What did your debugger show as the value of `name` after calling `toString()` on it? — Jonny Henly, Mar 03 '17 at 17:37
Does this compile? It looks like you have four quotes in your string literal, perhaps that's just SO's markdown script changing some UTF characters. — Jonny Henly, Mar 03 '17 at 17:44
doesn't look like it's the same character at all: `°˚` -> close as typo — njzk2, Mar 03 '17 at 17:46

You're checking 2 different characters, code point 176 vs 730

if (name.toString().contains("°")) {

Just copy the symbol from the CharSequence and paste inside the `contains` – Mar 03 '17 at 17:39

@Hugo indeed copy or Option + 0176 – Reimeus Mar 03 '17 at 17:44
@Andreas ok extended ASCII then :) – Reimeus Mar 03 '17 at 17:57
*"[Extended ASCII](https://en.wikipedia.org/wiki/Extended_ASCII)"*? Which one? Did you mean **Unicode**, perhaps? – Andreas Mar 03 '17 at 17:59
