We have an occasional caveat in our documentation about bracket components in the TeX fonts not being the sizes that the formatter expects.

This has consequences when we render those glyphs using the TeX fonts.

Figure out of there is a workaround for this.  Should \x get involved?

Possible complications:

  • The special characters that produce these glyphs appear in a tbl table.

  • The table appears in a man page, where portability considerations militate against extreme cleverness.

This problem also affects \[integral], \[sum], \[product], and \[coproduct].

Is this simply a problem with the font description files having the wrong metrics?  It may have been a long time since they were generated.  (I thought anything using Knuth's official names was frozen.)
