軔 Compatibility Form

A cart chock; by extension, “stop.”

The Han-era poem Changyang fu records 軔 as a chock; Zhan Guo Ce and Hou Hanshu, two classical works, use it for “stop.” 軔 also named a length of eight 尺 (chǐ), an old Chinese measure. In the poem Li Sao, 發軔 means removing the chock to set out, later figuratively “begin.”

Why keep 軔 separate?

It preserves one source code for conversion.

CNS 11643-1992 is Taiwan’s standard for exchanging Chinese text. 軔 is entry T4-302C, plane 4, cell 30-2C; keeping it lets conversion back restore that entry.
