  - getUnicode
```
public int getUnicode(int index)
```
    Gets unicode value for corresponding font's char code.
    
    Parameters:
    
    index - font's char code
    
    Returns:
    
    -1, if the char code unsupported or valid unicode.

  - convertToBytes
```
public byte[] convertToBytes(String text)
```
    Converts a String to a byte array according to the encoding. String could contain a unicode symbols or font specific codes.
    
    Parameters:
    
    text - the String to be converted.
    
    Returns:
    
    an array of byte representing the conversion according to the encoding
  - convertToByte
```
public int convertToByte(int unicode)
```
    Converts a unicode symbol or font specific code to byte according to the encoding.
    
    Parameters:
    
    unicode - a unicode symbol or FontSpecif code to be converted.
    
    Returns:
    
    a byte representing the conversion according to the encoding
  - canEncode
```
public boolean canEncode(int unicode)
```
    Check whether a unicode symbol or font specific code can be converted to byte according to the encoding.
    
    Parameters:
    
    unicode - a unicode symbol or font specific code to be checked.
    
    Returns:
    
    true if ch could be encoded.
  - canDecode
```
public boolean canDecode(int code)
```
    Check whether a byte code can be converted to unicode symbol according to the encoding.
    
    Parameters:
    
    code - a byte code to be checked.
    
    Returns:
    
    true if code could be decoded.
  - fillCustomEncoding
```
protected void fillCustomEncoding()
```
  - fillNamedEncoding
```
protected void fillNamedEncoding()
```
  - fillStandardEncoding
```
protected void fillStandardEncoding()
