Package-Level Type Names (total 7, in which 5 are exported)

	/* sort exporteds by: alphabet | popularity */
	 type CaseRange (struct)
		CaseRange represents a range of Unicode code points for simple (one
		code point to one code point) case conversion.
		The range runs from Lo to Hi inclusive, with a fixed stride of 1. Deltas
		are the number to add to the code point to reach the code point for a
		different case for that character. They may be negative. If zero, it
		means the character is in the corresponding case. There is a special
		case representing sequences of alternating corresponding Upper and Lower
		pairs. It appears with a fixed Delta of
			{UpperLower, UpperLower, UpperLower}
		The constant UpperLower has an otherwise impossible delta value.

		Fields (total 3, all are exported)
			Delta d
			Hi uint32
			Lo uint32
		As Inputs Of (at least one unexported)
			/* at least one unexported ... *//* at least one unexported: */
			func to(_case int, r rune, caseRange []CaseRange) (mappedRune rune, foundMapping bool)

	 type Range16 (struct)
		Range16 represents of a range of 16-bit Unicode code points. The range runs from Lo to Hi
		inclusive and has the specified stride.

		Fields (total 3, all are exported)
			Hi uint16
			Lo uint16
			Stride uint16
		As Inputs Of (at least one unexported)
			/* at least one unexported ... *//* at least one unexported: */
			func is16(ranges []Range16, r uint16) bool

	 type Range32 (struct)
		Range32 represents of a range of Unicode code points and is used when one or
		more of the values will not fit in 16 bits. The range runs from Lo to Hi
		inclusive and has the specified stride. Lo and Hi must always be >= 1<<16.

		Fields (total 3, all are exported)
			Hi uint32
			Lo uint32
			Stride uint32
		As Inputs Of (at least one unexported)
			/* at least one unexported ... *//* at least one unexported: */
			func is32(ranges []Range32, r uint32) bool

	 type RangeTable (struct)
		RangeTable defines a set of Unicode code points by listing the ranges of
		code points within the set. The ranges are listed in two slices
		to save space: a slice of 16-bit ranges and a slice of 32-bit ranges.
		The two slices must be in sorted order and non-overlapping.
		Also, R32 should contain only values >= 0x10000 (1<<16).

		Fields (total 3, all are exported)
			LatinOffset int
				// number of entries in R16 with Hi <= MaxLatin1

			R16 []Range16
			R32 []Range32

			func Is(rangeTab *RangeTable, r rune) bool
			func IsOneOf(ranges []*RangeTable, r rune) bool

Package-Level Functions (total 25, in which 21 are exported)

	 func In(r rune, ranges ...*RangeTable) bool
		In reports whether the rune is a member of one of the ranges.

	 func Is(rangeTab *RangeTable, r rune) bool
		Is reports whether the rune is in the specified table of ranges.

	 func IsControl(r rune) bool
		IsControl reports whether the rune is a control character.
		The C (Other) Unicode category includes more code points
		such as surrogates; use Is(C, r) to test for them.

	 func IsDigit(r rune) bool
		IsDigit reports whether the rune is a decimal digit.

	 func IsGraphic(r rune) bool
		IsGraphic reports whether the rune is defined as a Graphic by Unicode.
		Such characters include letters, marks, numbers, punctuation, symbols, and
		spaces, from categories L, M, N, P, S, Zs.

	 func IsLetter(r rune) bool
		IsLetter reports whether the rune is a letter (category L).

	 func IsLower(r rune) bool
		IsLower reports whether the rune is a lower case letter.

	 func IsMark(r rune) bool
		IsMark reports whether the rune is a mark character (category M).

	 func IsNumber(r rune) bool
		IsNumber reports whether the rune is a number (category N).

	 func IsOneOf(ranges []*RangeTable, r rune) bool
		IsOneOf reports whether the rune is a member of one of the ranges.
		The function "In" provides a nicer signature and should be used in preference to IsOneOf.

	 func IsPrint(r rune) bool
		IsPrint reports whether the rune is defined as printable by Go. Such
		characters include letters, marks, numbers, punctuation, symbols, and the
		ASCII space character, from categories L, M, N, P, S and the ASCII space
		character. This categorization is the same as IsGraphic except that the
		only spacing character is ASCII space, U+0020.

	 func IsPunct(r rune) bool
		IsPunct reports whether the rune is a Unicode punctuation character
		(category P).

	 func IsSpace(r rune) bool
		IsSpace reports whether the rune is a space character as defined
		by Unicode's White Space property; in the Latin-1 space
		this is
			'\t', '\n', '\v', '\f', '\r', ' ', U+0085 (NEL), U+00A0 (NBSP).
		Other definitions of spacing characters are set by category
		Z and property Pattern_White_Space.

	 func IsSymbol(r rune) bool
		IsSymbol reports whether the rune is a symbolic character.

	 func IsTitle(r rune) bool
		IsTitle reports whether the rune is a title case letter.

	 func IsUpper(r rune) bool
		IsUpper reports whether the rune is an upper case letter.

	 func SimpleFold(r rune) rune
		SimpleFold iterates over Unicode code points equivalent under
		the Unicode-defined simple case folding. Among the code points
		equivalent to rune (including rune itself), SimpleFold returns the
		smallest rune > r if one exists, or else the smallest rune >= 0.
		If r is not a valid Unicode code point, SimpleFold(r) returns r.

		For example:
			SimpleFold('A') = 'a'
			SimpleFold('a') = 'A'

			SimpleFold('K') = 'k'
			SimpleFold('k') = '\u212A' (Kelvin symbol, K)
			SimpleFold('\u212A') = 'K'

			SimpleFold('1') = '1'

			SimpleFold(-2) = -2

	 func To(_case int, r rune) rune
		To maps the rune to the specified case: UpperCase, LowerCase, or TitleCase.

	 func ToLower(r rune) rune
		ToLower maps the rune to lower case.

	 func ToTitle(r rune) rune
		ToTitle maps the rune to title case.

	 func ToUpper(r rune) rune
		ToUpper maps the rune to upper case.

	/* 4 unexporteds ... *//* 4 unexporteds: */
	 func is16(ranges []Range16, r uint16) bool
		is16 reports whether r is in the sorted slice of 16-bit ranges.

	 func is32(ranges []Range32, r uint32) bool
		is32 reports whether r is in the sorted slice of 32-bit ranges.

	 func isExcludingLatin(rangeTab *RangeTable, r rune) bool
	 func to(_case int, r rune, caseRange []CaseRange) (mappedRune rune, foundMapping bool)
		to maps the rune using the specified case mapping.
		It additionally reports whether caseRange contained a mapping for r.
