20. The method of claim 16 , further comprising rendering, in the at least one computing device, the text unit in the encoded text block in a user interface for at least one of a text reader application, an email application, a network browser application, a database application, or an operating system.
16. A method, comprising; receiving, in at least one computing device, an encoded text block, the encoded text block comprising text; identifying, in the at least one computing device, a first signal in the encoded text block, the first signal specifying a text unit corresponding to a series of characters in the text; rendering, in the at least one computing device, the text in the encoded text block; assigning, in the at least one computing device, a label to the text unit based at least upon content in the text unit; selecting, in the at least one computing device, an entirety of the series of characters in response to a first selection of a subset of the series of characters in the text unit; causing a text format of the text unit to be visually contrasted from a remainder of the text block; decoding the encoded text block to generate a decoded text block, the decoded text block comprising the series of characters bound as the text unit; and encoding, in response to a second selection of the subset of the series of characters in the decoded text block, the decoded text block to generate an additional encoded text block, the additional encoded text block comprising metadata indicating an unbinding of the series of characters as the text unit and a second signal specifying a removal of the label.
