UDO expects a text file which you can edit with every ASCII
editor. You should use only printable characters. That means you
shouldn't use any characters below
space except ASCII 9 (tab),
ASCII 10 (line feed) and ASCII 13 (carriage return). A text line in a
source file shouldn't contain more than 4092 characters.
UDO layouts the destination file itself. That means that it fills in spaces between words and lines between paragraphs:
You can compose the source file using different charsets.
When UDO starts the conversion it excepts the character set that
is used on the current operating system. If you want to convert source
documents which use other encodings, you have to inform UDO with the
relevant commands. Get more information about this in the chapter
