Which version of check_snmp are you using? 1.4.14 should have better
handling of special characters than anything before... whichever version
you use it would be nice it you could try the other (1.4.14 vs older).

Besides that I don't see what wouldn't work. Maybe try with debug output
(-vvv).

NB: check_snmp v1.4.14 has broken support for multiple -o option, but
you can still pass multiple oids separated with commas.
