Functions ¶

func Compose ¶

func Compose(a, b rune) (rune, bool)

Compose composes a sequence of two input Unicode code points by canonical equivalence, returning the composed code, if successful. It returns `false` otherwise

func Decompose ¶

func Decompose(ab rune) (a, b rune, ok bool)

Decompose decompose an input Unicode code point, returning the two decomposed code points, if successful. It returns `false` otherwise.

func HasArabicJoining ¶

func HasArabicJoining(script language.Script) bool

HasArabicJoining return 'true' if the given script has arabic joining.

func LookupCombiningClass ¶

func LookupCombiningClass(ch rune) uint8

LookupCombiningClass returns the class used for the Canonical Ordering Algorithm in the Unicode Standard, defaulting to 0.

From http://www.unicode.org/reports/tr44/#Canonical_Combining_Class: "This property could be considered either an enumerated property or a numeric property: the principal use of the property is in terms of the numeric values. For the property value names associated with different numeric values, see DerivedCombiningClass.txt and Canonical Combining Class Values."

func LookupMirrorChar ¶

func LookupMirrorChar(ch rune) (rune, bool)

LookupMirrorChar finds the mirrored equivalent of a character as defined in the file BidiMirroring.txt of the Unicode Character Database available at http://www.unicode.org/Public/UNIDATA/BidiMirroring.txt.

If the input character is declared as a mirroring character in the Unicode standard and has a mirrored equivalent, it is returned with `true`. Otherwise the input character itself returned with `false`.

Types ¶

type ArabicJoining ¶

type ArabicJoining byte

ArabicJoining is a property used to shape Arabic runes. See the table ArabicJoinings.

const (
	U          ArabicJoining = 'U' // Un-joining, e.g. Full Stop
	R          ArabicJoining = 'R' // Right-joining, e.g. Arabic Letter Dal
	Alaph      ArabicJoining = 'a' // Alaph group (included in kind R)
	DalathRish ArabicJoining = 'd' // Dalat Rish group (included in kind R)
	D          ArabicJoining = 'D' // Dual-joining, e.g. Arabic Letter Ain
	C          ArabicJoining = 'C' // Join-Causing, e.g. Tatweel, ZWJ
	L          ArabicJoining = 'L' // Left-joining, i.e. fictional
	T          ArabicJoining = 'T' // Transparent, e.g. Arabic Fatha
	G          ArabicJoining = 'G' // Ignored, e.g. LRE, RLE, ZWNBSP
)
