If you’d really just rather hand-code your LaTeX constructs, BBT makes that possible:
<script>...</script> (<pre>...</pre> will also work for historical reasons) markers. BBT will
convert to/from unicode and (un)escape where required but will pass whatever is enclosed in the pre tags unchanged.#LaTeX (case-sensitive!) will have all fields exported as if they’re wrapped in
<script>...</script>, so you can include LaTeX markup in your references.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.
