//str要替换的字符串//s1被替换的字符//s2替换的字符public String replaceAll(String str,char s1,char s2){ char[] cArray = str.toCharArray(); for(char c : cArray) { if(c == 's1') c = 's2'; } return String.valurOf(cArray);}

Answer 3

string.replace(str,"@@\","\\")就可以了
字符替换表 = {
["\"] = "\\";
["'"] = "<引号>";
["N"] = "n";
}

str = string.replace( "替换'这里的\N",".|:", 字符替换表 )

io.open();
io.print( str )

a=a.Replace("a","你要替换的字");
