UnicodeCharacters.IsGraphemeExtend | isGraphemeExtend method

Determines if a specified Unicode character can be considered to continue a previous grapheme.

Syntax


var boolean = Windows.Data.Text.UnicodeCharacters.isGraphemeExtend(codepoint);

Parameters

codepoint

Type: Number [JavaScript] | System.UInt32 [.NET] | uint32 [C++]

A Unicode character. This must be in the proper range: 0 <= codepoint <= 0x10FFFF.

Return value

Type: Boolean [JavaScript] | System.Boolean [.NET] | Platform::Boolean [C++]

TRUE if codepoint continues the previous grapheme; otherwise FALSE.

Remarks

This method determines if codepoint continues a previous grapheme per the Unicode Standard Annex #44. An example is a combining character or other character that is logically part of the previous character's shape.

See the remarks for GetCodepointFromSurrogatePair for a discussion of how to prepare a Unicode character to be passed to this method.

This method throws an invalid argument exception if the input is not a valid codepoint.
