Type Method

isValidUnicodeString(_:)isValidUnicodeString:error:isValidUnicodeString_error_

Checks whether a string uses the uppercase hexadecimal syntax for a Unicode code point.

class func isValidUnicodeString(_ unicode: String) throws
+ (BOOL) isValidUnicodeString:(NSString *) unicode error:(NSError **) error;
isValidUnicodeString_error_(unicode: str) -> tuple[bool, NSError]

Parameters

unicode

The proposed Unicode code point string.

Parameters

unicode

The proposed Unicode code point string.

error

On failure, an error describing the invalid string.

Discussion

This does not check whether the code point is already assigned to another glyph in the font.

Return Value

YES if the method succeeded, otherwise NO.
