bash - shell script “${array[@]}” expansion: first and last entry have extra characters -

i have shell script uses array. script cycle through entries of array reason first , last entry has problem.

the array:

queue_names=( clqueue dlq expiryqueue ) 

the loop:

for in “${queue_names[@]}”      #do stuff done  

i can see in console , shows first entry shows: �clqueue. last entry shows: expiryqueue�

i'm guessing these markers know start , end of array. unfortunately interfering functionality of script. use these queue names search , fails find because of added character. how rid of them or there code change avoid problem?

“${queue_names[@]}” not "${queue_names[@]}", because “” not "".

"smart quotes" aren't recognized quotes @ in bash; thus, effect same if expansion had been unquoted -- string-splitting , glob-expansion on array contents -- literal "quotes" grafted around start , end characters.

you need use real quotes -- "" -- not opening/closing "smart quotes" created word processing software or corporate email tools.
