Characters

String To UTF32 returns the code point (UTF-32 value) of a character or surrogate pair in a string.

Inputs

String (String)

The string to retrieve the character or surrogate pair from.

Index (int)

The 0-indexed character to retrieve from String.

This node deals with individual chars of a string, whether by way of indexing a string or by returning a char. This may result in unintuitive behavior with strings containing characters that reside outside the Basic Multilingual Plane, such as "mismatched" indices or returning an invalid char. For more information, see the type page for String.

Outputs

* (int)

The code point of the character or surrogate pair at the index in the string.

The value 0 is returned instead if one of the following is true:

  • String is null.
  • Index is greater than or equal to the String Length.
  • Index points to a low surrogate.
  • Index points to a high surrogate without a low surrogate following it.
