ENS for Calendar Server strange issue when handling special characters

Question

The problem is basically that the ENS message isn't fully flushed to the stream when the generated event (an appointment creation for example) has special characters such as "ñ", "á","é". Maybe are encoded in more than one byte but it flushes the buffer using characters * character_size and character_size is not always 1.
If I make a second appointment the buffer is flushed and I get the rest of the first notification and the new one.
Perhaps it is a configuration case and I should configure ENS to support more languages.
Could you help me?
Thank you,
Best regards.

Thank you Shane.
I've run the sample and it works fine.
Perhaps it's not a bug but it's very strange the behaviour ens has with events with special characters. This is what I do step by step:
1. I subscribe for all events and all the users
2. I create and appointment with special characters
3. I receive the event notification
GAP/1.0 1b 3 1915 enp:///ics/caleventcreate?calid=[email protected]&uid=000000000000000000000000000000000b2c934cc04e0000140000001f130000&rid=0|ntfy|00000000
The number 1915 should be the message length so I try to read 1915 bytes. However I can only read 1903 bytes. In this 1903 I have the full xml with the vcalendar.
4. I create a second appointment
5. The message I received is something like "\0\0\0\0\0\0\0\0\0\0\0\0" which is 1915-1903
6. I have to discard this message because it's invalid
7. I receive the event notification
I can fix my custom client and discard this "\0\0\0..." messages but It's a strange behaviour. Perhaps the protocol is as is but I thought it was a bug.
Thank you Shane.
