    @joewitt For Non-Uniform charset attached piece should work.
    
    ```java
    /**
         * @param rawBytes
         * @param patternToMatch
         * @return
         */
        private static boolean matchPattern(byte[] rawBytes , final String 
patternToMatch){
            out.println("Pattern= "+patternToMatch);
            final Pattern pattern = Pattern.compile(patternToMatch);
            final int patternByteLength=patternToMatch.getBytes().length;
            out.println("PatternByteLength= "+patternByteLength); 
            final int minSliceByteLength=2;
            final int sliceByteLength = patternByteLength > minSliceByteLength 
? patternByteLength : minSliceByteLength;
            int offset = 0;
            while (offset <= rawBytes.length) {
                String s=new String(Arrays.copyOfRange(rawBytes, 
offset>patternByteLength? offset-(patternByteLength+1):0,
                                                       (offset + 
sliceByteLength)));
                out.println("Retrieved byte[]= "+s);
                if (pattern.matcher(s).find()) {
                    return true;
                }
                offset += sliceByteLength;
            };
            return false;
        }
    ```
    
    I tried with \:
    ```java
    
matchPattern("I♥NY♥Y♥NABCDdkk;lskiepdmclod;die;'cnjywkl;sfdsXRSHSY♥♥Y".getBytes(),
 "♥♥Y");
    ```
