Is caused by using the example in the vlogger’s man file which contains a non-standard (at least for my system) pipe character:

CustomLog “? /usr/sbin/vlogger -s access.log -u www-logs -g www-logs /var/log/apache” combined

Apparently the “\xe2\x8e\xaa” is UTF-8 encoding for a character that looks like a pipe (i.e. “|”) but in fact is not seen as a pipe on my linux system (I’m using Ubuntu). (See http://www.utf8-chartable.de/unicode-utf8-table.pl?start=9088&number=128&names=-&utf8=string-literal)

The following shows two pipe-like characters together (the first being the one from the man file, the second is a pipe I typed from my keyboard):

CustomLog “?| /usr/sbin/vlogger -s access.log -u www-logs -g www-logs /var/log/apache” combined

They should look look slightly different to you.

Replace the man file’s pipe character in the CustomLog example with a pipe from your keyboard - and apache should restart without complaint.
