How to convert '\u0301' to '\u0301'
php小编草莓为您介绍如何将字符串中的“\\u0301”转换为“\u0301”。在PHP中,可以使用str_replace函数来实现这个转换。具体操作是将字符串中的“\\u0301”替换为“\u0301”,代码如下: ``` $str = "\\u0301"; $newStr = str_replace("\\\\u", "\\u", $str); echo $newStr; ``` 通过这段代码,我们可以将字符串中的“\\u0301”转换为“\u0301”。这样就可以实现我们的需求了。希望以上内容对您有所帮助!
问题内容
我遇到的问题是
给定一个字符串包含几个特殊的子字符串,例如:
"\\u0301""\\b""\\t"
,..etc
请将以上所有特殊字符串转换为 "\u0301","\b","\t"
, ..etc
请注意,如果只是删除此处的反斜杠,
你会得到 "\u0301"
的明文,
而是 unicode 的重音符号。
一对一的解决方案是替换每个特殊字符串
str = strings.Replace(str, "\\u0301","\u0301", -1)
是所有转义字符代码的通用解决方案吗?
解决方法
如果需要将包含转义 unicode 序列和控制序列的字节序列转换为 unicode 字符串,则可以使用 strconv.unquote 函数。
为此,请将字节转换为字符串,转义双引号和换行符,并在此字符串的开头和结尾添加双引号字符。
package main import ( "fmt" "strconv" "strings" ) func main() { b := []byte{65, 92, 117, 48, 51, 48, 49, 9, 88, 10, 34, 65, 34} // the same as // b := []byte("a\\u0301\tx\n\"a\"") // convert to string s := string(b) fmt.println(s) fmt.println("=========") // escape double quotes s = strings.replaceall(s, "\"", "\\\"") // escape newlines s = strings.replaceall(s, "\n", "\\n") r, err := strconv.unquote(`"` + s + `"`) if err != nil { panic(err) } fmt.println(r) fmt.println("=========") }
输出:
A\u0301 X "A" ========= Á X "A" =========
