tag2command over-escaping brackets?

in drutex.module:

from _drutex_create_regex , lines 328-339:

switch ($entity->type) {
...
case 'tag2command':
...
$replacement = "\\\\$replacement\{\$2}";

It seems that when using tag2command to render PDFs, it generates TeX code like:
\textbf\{text here} instead of \textbf{text here}

Is the tag2command case used anywhere but the PDF rendering?

After unescaping the open bracket in the reported line, our PDFs are generated fine, with HTML properly rendered, but I haven't found exactly what this breaks just yet...

Anyone else encounter this?
