REST: Special characters in custom fields

I am using the REST interface to create and update tickets, as described in the wiki (REST - Request Tracker Wiki). However, I am running into a problem with some custom fields that have a hash/pound symbol (#) as part of the name. Other custom fields work fine.

For example, when attempting to update a ticket I get a response like this:

RT/3.8.1 409 Syntax Error

Syntax error.

cf-A Custom Field: aaa

cf-Another Field #: 123
cf-Contact Name: Ryan

I get the same error whether I url encode the data or not. Is there a special way to escape or encode special characters to avoid this error?

Thanks,
Ryan

Have you made it work with bin/rt and looked at the generated data
using RTDEBUG=3 bin/rt ?
