ODSEE - Is "%" String Allowed in 'ldapsearch' Request? (Doc ID 1433281.1)

Goal

Why do search requests containing fail while \20 works.

for example, the following works. \20 is the escape sequence for a space.
# ldapsearch -D "cn=<DS_ADMIN>" -w password -p <PORT> -b "ou=Company\20Servers,dc=<SUFFIX>" objectclass=\* dn
version: 1
dn: ou=Company Servers,dc=<SUFFIX>

but a search containing %xx fails with "No such object", why?

# ldapsearch -D "cn=<DS_ADMIN>" -w password -p <PORT> -b "ou=Company%xxServers, dc=<SUFFIX>" objectclass=\*
ldap_search: No such object
ldap_search: matched: dc=<SUFFIX>

The corresponding access log entry.
NOTE - This example is through a DPS instance but the same is true for the DS.
