Use:

Stringresult=EmojiParser.removeAllEmojis(input);

Okay,butIwilljustnotethattheemojiinyourquestionareoutsidethatrange!:-)
Thefactthattheseareabove0xFFFFcomplicatesthings,becauseJavastringsstoreUTF-16.Sowecan'tjustuseonesimplecharacterclassforit.We'regoingtohavesurrogatepairs.(More:http://www.unicode.org/faq/utf_bom.html)
U+1F300inUTF-16endsupbeingthepair\uD83C\uDF00;U+1F5FFendsupbeing\uD83D\uDDFF.Notethatthefirstcharacterwentup,wecrossatleastoneboundary.Sowehavetoknowwhatrangesofsurrogatepairswe'relookingfor.
NotbeingsteepedinknowledgeabouttheinnerworkingsofUTF-16,Iwroteaprogramtofindout(sourceattheend —I'ddouble-checkitifIwereyou,ratherthantrustingme).Ittellsmewe'relookingfor\uD83Cfollowedbyanythingintherange\uDF00-\uDFFF(inclusive),or\uD83Dfollowedbyanythingintherange\uDC00-\uDDFF(inclusive).
Soarmedwiththatknowledge,intheorywecouldnowwriteapattern:
//Thisiswrong,keepreading
Patternp=Pattern.compile("(?:\uD83C[\uDF00-\uDFFF])|(?:\uD83D[\uDC00-\uDDFF])");
That'sanalternationoftwonon-capturinggroups,thefirstgroupforthepairsstartingwith\uD83C,andthesecondgroupforthepairsstartingwith\uD83D.
Butthatfails(doesn'tfindanything).I'mfairlysureit'sbecausewe'retryingtospecifyhalfofasurrogatepairinvariousplaces:
Patternp=Pattern.compile("(?:\uD83C[\uDF00-\uDFFF])|(?:\uD83D[\uDC00-\uDDFF])");
//Halfofapair--------------^------^------^-----------^------^------^
Wecan'tjustsplitupsurrogatepairslikethat,they'recalledsurrogatepairsforareason.:-)
Consequently,Idon'tthinkwecanuseregularexpressions(orindeed,anystring-basedapproach)forthisatall.Ithinkwehavetosearchthroughchararrays.
chararraysholdUTF-16values,sowecanfindthosehalf-pairsinthedataifwelookforitthehardway:
Strings=newStringBuilder()
.append("Thatsanicejoke")
.appendCodePoint(0x1F606)
.appendCodePoint(0x1F606)
.appendCodePoint(0x1F606)
.append("")
.appendCodePoint(0x1F61B)
.toString();
char[]chars=s.toCharArray();
intindex;
charch1;
charch2;
index=0;
while(index=0xDF00&&(int)ch2<=0xDFFF){
System.out.println("Foundemojiatindex"+index);
index+=2;
continue;
}
}
elseif((int)ch1==0xD83D){
ch2=chars[index+1];
if((int)ch2>=0xDC00&&(int)ch2<=0xDDFF){
System.out.println("Foundemojiatindex"+index);
index+=2;
continue;
}
}
++index;
}
Obviouslythat'sjustdebug-levelcode,butitdoesthejob.(Inyourgivenstring,withitsemoji,ofcourseitwon'tfindanythingasthey'reoutsidetherange.Butifyouchangetheupperboundonthesecondpairto0xDEFFinsteadof0xDDFF,itwill.Noideaifthatwouldalsoincludenon-emojis,though.)
Sourceofmyprogramtofindoutwhatthesurrogaterangeswere:
publicclassFindRanges{
publicstaticvoidmain(String[]args){
charlast0='\0';
charlast1='\0';
for(intx=0x1F300;x<=0x1F5FF;++x){
char[]chars=newStringBuilder().appendCodePoint(x).toString().toCharArray();
if(chars[0]!=last0){
if(last0!='\0'){
System.out.println("-\\u"+Integer.toHexString((int)last1).toUpperCase());
}
System.out.print("\\u"+Integer.toHexString((int)chars[0]).toUpperCase()+"\\u"+Integer.toHexString((int)chars[1]).toUpperCase());
last0=chars[0];
}
last1=chars[1];
}
if(last0!='\0'){
System.out.println("-\\u"+Integer.toHexString((int)last1).toUpperCase());

}
}
Output:
