Not when they're enclosed in double quotes. The opposite isn't true.

Code:
A=" '1 2 3' "

echo "$A"
'1 2 3'

A=' "1 2 3" '
echo $A
"1 2 3"

echo '$A'
$A

ATRUN(8)						    BSD System Manager's Manual 						  ATRUN(8)

NAME
atrun -- run jobs queued for later execution SYNOPSIS
atrun [-l load_avg] [-d] DESCRIPTION
atrun runs jobs queued by at(1). Root's crontab(5) must contain the line: */10 * * * * root /usr/libexec/atrun so that atrun(8) gets called every ten minutes. At every invocation, every job in lowercase queues whose starting time has passed is started. A maximum of one batch job (denoted by upper- case queues) is started each time atrun is invoked. OPTIONS
-l load_avg Specifies a limiting load factor, over which batch jobs should not be run, instead of the compiled-in value of 1.5. -d Debug; print error messages to standard error instead of using syslog(3). WARNINGS
For atrun to work, you have to start up a cron(8) daemon. FILES
/var/at/spool Directory containing output spool files /var/at/jobs Directory containing job files SEE ALSO
at(1), crontab(1), syslog(3), crontab(5), cron(8) AUTHORS
Thomas Koenig <ig25@rz.uni-karlsruhe.de> BUGS
The functionality of atrun should be merged into cron(8). BSD
