I'm looking for java tool for converting regular String to utf-8 string.
eg
input: special-数据应用-text
output: special-%u6570%u636E%u5E94%u7528-text
(note the preceding "%u")
Two things:
The string you want as result is not UTF-8, at least the string you put as example is sort of UTF-16 encoded (java uses UTF-16 internally)
An example of code that gives you the string that you want:
String str = "special-数据应用-text"; StringBuilder builder = new StringBuilder(); for(char ch: str.toCharArray()) { if(ch >= 0x20 && ch <= 0x7E) { builder.append(ch); } else { builder.append(String.format("%%u%04X", (int)ch)); } } String result = builder.toString();
Let me recommend you Unbescape [ http://www.unbescape.org ]
Among other escaping operations (HTML, XML, etc.), it will allow you to escape your Java literal with:
final String escaped = JavaEscape.escapeJava(text);
Disclaimer, per StackOverflow rules: I'm Unbescape's author.
Can you try the following
StringBuilder b = new StringBuilder();
for( char c : s.toCharArray() ){
if( ( 1024 <= c && c <= 1279 ) || ( 1280 <= c && c <= 1327) || ( 11744 <= c && c <= 11775) || ( 42560 <= c && c <= 42655) ){
b.append( "\\u" ).append( Integer.toHexString(c) );
}else{
b.append( c );
}
}
return b.toString();
Found here
尝试这个
String s= URLEncoder.encode(str, "UTF-8").replaceAll("%(..)%(..)", "%u$1$2");
