StringtoAsciiFilename(String string)
to Ascii Filename 
return string.replaceAll("[^0-9a-zA-Z-.]", "_");
chartoAsciiLowerCase(char ch)
Converts the specified character to lower case if it is a valid latin letter, otherwise the same character is returned. 
if ((ch >= 'A') && (ch <= 'Z')) {
    return (char) (ch + 'a' - 'A');
} else {
    return ch;
StringtoAsciiString(byte[] buffer)
Returns the bytes as an ASCII String. 
return toAsciiString(buffer, 0, buffer.length);
StringtoAsciiString(byte[] buffer, int startPos, int length)
to Ascii String 
char[] charArray = new char[length];

StringtoASCIIString(byte[] data)
Produces a string using each byte as an ASCII character 
if (data == null) {

to Ascii String 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < s.length(); i++) {
    char c = s.charAt(i);
    if (c > 127) {
        sb.append(toUnicodeStr(c));
    } else {
        sb.append((char) c);

StringtoAsciiString(String value)
to Ascii String
