One aspect of this standard is the use of encoded words, which are sequences of ASCII characters that represent non-ASCII text. However, when folding white space is used in the encoded words, some email clients and servers may incorrectly handle the decoding of the text. Folding white space is when a line break is inserted in the middle of a long string of text to make it fit within a certain line length limit. If an encoded word with folding white space is not correctly handled during decoding, it may result in garbled text or even a security vulnerability if the text is used in a context where it should not be. This can happen because different email clients and servers may interpret folding white space differently.
