Variants of Uuencoding

There are many variations of the above rules which must be taken into account in a decoder program. Here are the most frequent:

There is also some confusion how to properly terminate a line. Most encoders simply use the convention of the local system (DOS encoders using CRLF, Unix encoders using LF, Mac encoders using CR), but with respect to the MIME standard, the encoding library uses CRLF on all systems. This causes a slight problem with some Unix decoders, which look for ``end'' followed directly by LF (as four characters in total). Such programs report ``end not found'', but nevertheless decode the file correctly.
