英文:
Ignore character accents when sorting strings
问题
我正在编写一个使用Go语言的程序，它接受一个字符串列表，并将它们按照字符串的首字母分组到桶列表中。然而，我希望它能将带重音符号的字符与最相似的无重音字符分组在一起。所以，如果我有一个以字母A为键的桶，我希望以Á开头的字符串也能被包括进去。
Go语言中是否有内置的方法可以确定这一点，或者我最好的选择是使用一个包含所有字符及其带重音变体的大型switch语句？
英文:
I'm writing a golang program, which takes a list of strings and sorts them into bucket lists by the first character of string. However, I want it to group accented characters with the unaccented character that it most resembles. So, if I have a bucket for the letter A, then I want strings that start with Á to be included.
Does Go have anything built-in for determining this, or is my best bet to just have a large switch statement with all characters and their accented variations?

看起来有一些附加包可以使用。这里是一个示例...
package main
import (
"fmt"
"golang.org/x/text/collate"
"golang.org/x/text/language"
)
func main() {
strs := []string{"abc", "áab", "aaa"}
cl := collate.New(language.English, collate.Loose)
cl.SortStrings(strs)
fmt.Println(strs)
}
输出结果:
[aaa áab abc]
此外，可以查看以下关于文本规范化的参考资料：

Looks like there are some addon packages for this. Here's an example...
package main
import (
"fmt"
"golang.org/x/text/collate"
"golang.org/x/text/language"
)
func main() {
strs := []string{"abc", "áab", "aaa"}
cl := collate.New(language.English, collate.Loose)
cl.SortStrings(strs)
fmt.Println(strs)
}
outputs:
[aaa áab abc]
