fromCodePoint

fromCodePoint

> Functions

Returns the single-character string whose unicode codepoint is codePoint: fromCodePoint(65) returns "A". It is the inverse of codePointAt.

Codepoints above 65535 give characters such as emojis: fromCodePoint(128040) returns "🐨".

Parameters

• codePoint: The unicode codepoint, from 0 to 1114111 (0x10FFFF), except 55296 to 57343 (0xD800 to 0xDFFF), which are reserved for surrogate halves.

Return

• string: The character, or null if codePoint is not a valid codepoint.

Note

• A codepoint that is negative, above 1114111 or between 55296 and 57343 returns null.
• A character above 65535 counts for 2 in length and takes two indexes for codePointAt and charAt.
• In JavaScript, String.fromCodePoint throws a RangeError outside 0 to 1114111, and chr throws a ValueError in Python.
• Costs 6 operations. See also codePointAt and charAt.
