[

1. Used to create digraphs that substitute for letters that do not have proper Unicode support

Usage notes

The digraphs [B, [b, [D, [d, [G, [g replace overstruck B̶, b̶, D̶, d̶, G̶, g̶, which do not have dedicated Unicode support. More documents (including official government publications) use the bracket hack than the single letters.
