Null byte in regex

[nijel]

This seems to happen only in master on tbl_structure.php:

Warning in ./tmp/twig/0d/0da6a0b8ecebb7575f70f472e5b82aea3f679c74e92c76aa5274ed8f6f9e33f8.php#181
preg_replace(): Null byte in regex

It seems to be coming from here:

Lines 74 to 78 in 22d068c

	'displayed_field_name': preg_replace(
