Editing UTF-7 (section)

===Decoding===
First an encoded data must be separated into plain ASCII text chunks (including '''+'''es followed by a dash) and nonempty Unicode blocks as mentioned in the description section. Once this is done, each Unicode block must be decoded with the following procedure (using the result of the encoding example above as our example)

#Express each Base64 code as the bit sequence it represents:<br /><samp>AKMgIA → 000000 001010 001100 100000 001000 000000</samp>
#Regroup the binary into groups of sixteen bits, starting from the left:<br /><samp>000000 001010 001100 100000 001000 000000 → 0000000010100011 0010000000100000 0000</samp>
#If there is an incomplete group at the end containing only zeros, discard it (if the incomplete group contains any ones, the code is invalid):<br /><samp>0000000010100011 0010000000100000</samp>
#Each group of 16 bits is a character's Unicode (UTF-16) number and can be expressed in other forms:<br /><samp>0000 0000 1010 0011 ≡ 0x00A3 ≡ 163<sub>10</sub></samp>
