You are a hardcore LaTeX user

If you’d really just rather hand-code your LaTeX constructs, BBT makes that possible:

• You can add literal LaTeX anywhere in your reference by surrounding it with <pre>....</pre> tags. BBT will convert to/from unicode and (un)escape where required but will pass whatever is enclosed in the pre tags unchanged.
• An entry tagged with #LaTeX (case-sensitive!) will have all fields exported as if they’re wrapped in <pre>...</pre>, so you can include LaTeX markup in your references.

Gotchas

• In names, you can force first names like Philippe to be exported to {\relax Ph}ilippe (which causes it to get initial Ph. rather than P. in styles that do initials) by adding a end of guarded area character between Ph and ilippe.
