guess7BitEncoding

public void guess7BitEncoding()

Tries to identify the correct encoding for 7-bit (non-unicode) strings in the file.

Many messages store their strings as unicode, which is nice and easy. Some use one-byte encodings for their strings, but don't always store the encoding anywhere helpful in the file.

This method checks for codepage properties, and failing that looks at the headers for the message, and uses these to guess the correct encoding for your file.

Bug #49441 has more on why this is needed

set7BitEncoding

public void set7BitEncoding(String charset)

Many messages store their strings as unicode, which is nice and easy. Some use one-byte encodings for their strings, but don't easily store the encoding anywhere in the file! If you know what the encoding is of your file, you can use this method to set the 7 bit encoding for all the non unicode strings in the file.

See Also:

guess7BitEncoding()

has7BitEncodingStrings

public boolean has7BitEncodingStrings()

Does this file contain any strings that are stored as 7 bit rather than unicode?
