Expdp with special character # password resulting in error - oracle

Question

I have set of new boxes where I need to take a copy of export ,
All of this machines have system user password with complex stuff like# etc..
Ex:
expdp system/yada#yada1233*something #hostname:portnumber/servicename
schemas=soso directory=xyz dumpfile=mydump.dmp logfile=mylog.log
ERROR:
UDE-12154:opertion generated oracle error 12154
ORA-12154:TNS:could not resolve the connect identifier specified
Yeah I know this looks like service name resolution issue but tnsping looks good and is able to resolve I believe this has to do with password having #I have tried putting the password in double quotes adding escape character to special characters etc but none work any guidance would be great
Also I tried with user that don't have special characters it works fine
edit : As Suggested here are things I tried and didn't work and still threw the same error
expdp system/'yada#yada1233*something' #hostname:portnumber/servicename
schemas=soso directory=xyz dumpfile=mydump.dmp logfile=mylog.log
expdpsystem/"yada#yada1233*something*"#hostname:portnumber/servicename schemas=soso directory=xyz dumpfile=mydump.dmp logfile=mylog.log
expdp system/\"yada#yada1233*something\" #hostname:portnumber/servicename
schemas=soso directory=xyz dumpfile=mydump.dmp logfile=mylog.log
expdp system/"yada\#yada1233\*something" #hostname:portnumber/servicename
schemas=soso directory=xyz dumpfile=mydump.dmp logfile=mylog.log
