ParseInt this Symbol

Question

 <-- how to find the bit configuration for this symbol (even in a decimal or hexadecimal form)? or isn't it a char? I need to check if it is present in a string. Any suggestion for resolving this?

Put this into the "Expression" input at the top: "".charCodeAt(0)

The value will be 65532 (*note), and the INTERNAL (IEEE-754) float representation (bits and hex) are shown in the middle boxes.

edit: Using parseInt (EXTERNAL representation) they're :
alert(parseInt("".charCodeAt(0)).toString(2)); // binary
alert(parseInt("".charCodeAt(0)).toString(16)); // hexadecimal

* Note, 0xfffc (65532) is the Unicode replacement character for encoding errors (it's corrupt).

.

Answer 2

Use codePointAt() method, which returns a non-negative integer Unicode code point value.

eg:

document.write(String.fromCodePoint(65532, 9731, 9733, 9842, 0x2F804));
// expected output: "☃★♲你"

document.write("<br><br>");

var icons = '☃★♲';

document.write(icons.codePointAt(0));
// expected output: "65532"

Answer 3

Incrible code, Kirk Schafer!
Suraj, that is what I was looking for!
thank you 2!!!

Answer 4

my brain exploded looking at that

Answer 5

[note] Edited to clarify internal vs external representation of IEEE-754 floats after reviewing what was desired.
