概观
打包unicode提供数据和函数来测试 Unicode 代码点的一些属性。
示例（Is）
以“Is”开头的函数可用于检查符文属于哪个范围的表格。请注意，符文可能适用于多个范围。

CaseRanges内的 Delta 数组索引，用于大小写映射。
const ( UpperCase = iota LowerCase TitleCase MaxCase)
如果一个 CaseRange 的 Delta 字段是 UpperLower，则意味着这个 CaseRange 表示一个形式的序列（比如说） Upper Lower Upper Lower 。
const ( UpperLower = MaxRune + 1 // (Cannot be a valid delta.))

func SimpleFold
func SimpleFold(r rune) rune
SimpleFold 在 Unicode 定义的简单大小写折叠下迭代 Unicode 代码点。在相当于符文的代码点（包括符文本身）中，SimpleFold返回最小的符文> r，否则最小的符文> = 0.如果r不是有效的 Unicode 代码点，则 SimpleFold（r） 返回 r。
例如：
SimpleFold('A') = 'a'SimpleFold('a') = 'A'SimpleFold('K') = 'k'SimpleFold('k') = '\u212A' (Kelvin symbol, K)SimpleFold('\u212A') = 'K'SimpleFold('1') = '1'SimpleFold(-2) = -2示例
package mainimport ("fmt""unicode")func main() {
fmt.Printf("%#U\n", unicode.SimpleFold('A')) // 'a'
fmt.Printf("%#U\n", unicode.SimpleFold('a')) // 'A'
fmt.Printf("%#U\n", unicode.SimpleFold('K')) // 'k'
fmt.Printf("%#U\n", unicode.SimpleFold('k')) // '\u212A' (Kelvin symbol, K)
fmt.Printf("%#U\n", unicode.SimpleFold('\u212A')) // 'K'
fmt.Printf("%#U\n", unicode.SimpleFold('1')) // '1'}func To
func To(_case int, r rune) rune
将符号映射到指定的情况：UpperCase， LowerCase 或 TitleCase。
示例
package mainimport ("fmt""unicode")func main() {const lcG = 'g'
fmt.Printf("%#U\n", unicode.To(unicode.UpperCase, lcG))
fmt.Printf("%#U\n", unicode.To(unicode.LowerCase, lcG))
fmt.Printf("%#U\n", unicode.To(unicode.TitleCase, lcG))const ucG = 'G'
fmt.Printf("%#U\n", unicode.To(unicode.UpperCase, ucG))
fmt.Printf("%#U\n", unicode.To(unicode.LowerCase, ucG))
fmt.Printf("%#U\n", unicode.To(unicode.TitleCase, ucG))}func ToLower
func ToLower(r rune) rune
ToLower 将符文映射为小写字母。
示例
package mainimport ("fmt""unicode")func main() {const ucG = 'G'
fmt.Printf("%#U\n", unicode.ToLower(ucG))}func ToTitle
func ToTitle(r rune) rune
ToTitle 将符文映射到标题大小写。
示例
package mainimport ("fmt""unicode")func main() {const ucG = 'g'
fmt.Printf("%#U\n", unicode.ToTitle(ucG))}func ToUpper
func ToUpper(r rune) rune
ToUpper 将符文映射为大写。
示例
package mainimport ("fmt""unicode")func main() {const ucG = 'g'
fmt.Printf("%#U\n", unicode.ToUpper(ucG))}键入 CaseRange
CaseRange 表示简单（一个代码点到一个代码点）大小写转换的一系列 Unicode 代码点。范围从 Lo 到 Hi 包含，固定步幅为 1. Deltas 是要添加到代码点以达到该角色不同情况的代码点的数字。他们可能是消极的。如果为零，则表示该角色处于相应的情况。有一个特殊情况代表交替对应的上和下对的序列。它与一个固定的 Delta 相似
{UpperLower, UpperLower, UpperLower}常数 UpperLower 具有不可能的增量值。
type CaseRange struct {
Lo uint32
Hi uint32
Delta d}键入 Range16
Range16 表示一系列16位 Unicode 代码点。范围从 Lo 到 Hi 包含并且具有指定的步幅。
type Range16 struct {
Lo uint16
Hi uint16
Stride uint16}键入 Range32
Range32 代表一系列 Unicode 代码点，当一个或多个值不适合16位时使用。范围从 Lo 到 Hi 包含并且具有指定的步幅。 Lo 和 Hi 必须始终> = 1 << 16。
type Range32 struct {
Lo uint32
Hi uint32
Stride uint32}键入 RangeTable
RangeTable 通过列出集合中代码点的范围来定义一组 Unicode 代码点。范围在两个切片中列出以节省空间：16位范围片段和32位范围片段。这两个切片必须按排序顺序且不重叠。另外，R32 应该只包含 > = 0x10000（1 << 16） 的值。
type RangeTable struct {
R16 []Range16
R32 []Range32
LatinOffset int // number of entries in R16 with Hi <= MaxLatin1}键入 SpecialCase
SpecialCase 代表语言特定的案例映射，如土耳其语。SpecialCase 的方法自定义（通过覆盖）标准映射。
type SpecialCase []CaseRange
var AzeriCase SpecialCase = _TurkishCase
var TurkishCase SpecialCase = _TurkishCase
示例
package mainimport ("fmt""unicode")func main() {
t := unicode.TurkishCaseconst lci = 'i'
fmt.Printf("%#U\n", t.ToLower(lci))
fmt.Printf("%#U\n", t.ToTitle(lci))
fmt.Printf("%#U\n", t.ToUpper(lci))const uci = 'İ'
fmt.Printf("%#U\n", t.ToLower(uci))
fmt.Printf("%#U\n", t.ToTitle(uci))
fmt.Printf("%#U\n", t.ToUpper(uci))}func (SpecialCase) ToLower
func (special SpecialCase) ToLower(r rune) rune
ToLower 将符文映射为小写，优先考虑特殊映射。
func (SpecialCase) ToTitle
func (special SpecialCase) ToTitle(r rune) rune
ToTitle 将符文映射为标题情况，优先考虑特殊映射。
func (SpecialCase) ToUpper
func (special SpecialCase) ToUpper(r rune) rune
ToUpper 将符文映射为大写，优先考虑特殊映射。
错误
☞ 没有完整大小写折叠的机制，也就是说，对于在输入或输出中涉及多个符文的字符。
