[AGENT++] [SNMP++] Longer than expected response with unprintable characters

[Jochen Katz]

Hi,

you obviously use the get_printable() function, that behaves as desired. 
If the string contains nonprintable characters, the output of 
get_printable_hex() is returned.
See http://sa-ha.de/tmp_doc/classOctetStr.html#a17

If you want the raw value, you have to use data() and len() functions.

Regards,
   Jochen
