goog.i18n.uChar

Composes a supplementary Unicode code point from the given UTF-16 surrogate pair. If leadSurrogate isn't a leading surrogate code point or trailSurrogate isn't a trailing surrogate code point, null is returned.

Determines the length of the string needed to represent the specified Unicode code point.

Gets a character from the given Unicode value. If the given code point is not a valid Unicode code point, null is returned.

Returns the Unicode code point at the specified index.

If the char value specified at the given index is in the leading-surrogate range, and the following index is less than the length of string, and the char value at the following index is in the trailing-surrogate range, then the supplementary code point corresponding to this surrogate pair is returned.

If the char value specified at the given index is in the trailing-surrogate range, and the preceding index is not before the start of string, and the char value at the preceding index is in the leading-surrogate range, then the negated supplementary code point corresponding to this surrogate pair is returned.

The negation allows the caller to differentiate between the case where the given index is at the leading surrogate and the one where it is at the trailing surrogate, and thus deduce where the next character starts and preceding character ends.

Otherwise, the char value at the given index is returned. Thus, a leading surrogate is returned when it is not followed by a trailing surrogate, and a trailing surrogate is returned when it is not preceded by a leading surrogate.

Gets whether the given code point is a leading surrogate character.

Determines whether the specified Unicode code point is in the supplementary Unicode characters range.

Gets whether the given code point is a trailing surrogate character.

Gets Unicode value of the given character.

Gets the U+ notation string of a Unicode character. Ex: 'U+0041' for 'A'.
