Method

StringtoUTF8(String isoString)
Convert ISO8859-1 format string (which is the default sent by IE to the UTF-8 format that the database is in. 
String utf8String = null;
if (null != isoString && !isoString.equals("")) {
    try {
        byte[] stringBytesISO = isoString.getBytes("ISO-8859-1");
        utf8String = new String(stringBytesISO, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        System.out.println("UnsupportedEncodingException is: " + e.getMessage());
        utf8String = isoString;
...
StringtoUTF8(String s)
Encodes a string to UTF8 
if (s != null) {
    try {
        return new String(s.getBytes("UTF8"));
    } catch (UnsupportedEncodingException e) {
return null;
StringtoUTF8(String sourceStr)
to UTF 
return changeEncoding(sourceStr, "ISO8859-1", "UTF-8");
StringtoUTF8(String str)
to UTF 
try {
    return URLEncoder.encode(str, "UTF-8").replace("%2F", "/").replace("+", " ");
} catch (UnsupportedEncodingException ex) {
    return str;
byte[]toUTF8(String str)
Converts the string to a UTF-8 byte array, turning the checked exception (which should never happen) into a runtime exception. 
try {
    if (str == null)
        return new byte[0];
    return str.getBytes("UTF-8");
} catch (UnsupportedEncodingException e) {
    throw new RuntimeException("UTF-8 not supported", e);
StringtoUtf8(String str)
to Utf 
String val = "";
try {
    val = new String(str.getBytes("UTF-8"), "UTF-8");
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
return val;
StringtoUTF8(String str)
to UTF 
if (!isNull(str)) {
    try {
        str = new String(str.getBytes("ISO8859-1"), "UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
return str;
...
byte[]toUTF8(String string)
Convert from a String to UTF-8 bytes. 
if (string == null) {
    return null;
try {
    return string.getBytes(UTF_8_ENCODING);
} catch (UnsupportedEncodingException e) {
    throw new IllegalStateException("UTF-8 not supported?", e);
StringtoUTF8(String value)
to UTF 
if (value == null) {
    return "";
byte[] b = value.getBytes("ISO-8859-1");
return new String(b, "utf-8");
byte[]toUTF8ByteArray(char[] string)
to UTF Byte Array 
ByteArrayOutputStream bOut = new ByteArrayOutputStream();
try {
    toUTF8ByteArray(string, bOut);
} catch (IOException e) {
    throw new IllegalStateException("cannot encode string to byte array!");
return bOut.toByteArray();
