6. A system, comprising: at least one computing device; and a plurality of computer instructions executable by the at least one computing device, wherein the plurality of computer instructions, when executed, cause the at least one computing device to at least: designate a series of characters in a text block as being a text unit; bind the series of characters together; encode the text block to generate an encoded text block, the encoded text block comprising a first signal indicating that an entirety of the series of characters in the text unit is to be selected in response to a subset of the series of characters being selected; select, in response to the first signal and at least a portion of the subset of the series of characters being selected, the entirety of the series of characters in the text unit; and encode, in response to an instruction to treat the series of characters as being unbound, the text block to generate a modified encoded text block, wherein the modified encoded text block comprises a second signal indicating that a portion of the series of characters is to be selected in response to the portion of the series of characters being selected.
