CMA 24.10.16 Windows - No data sent to poller due to UTF-8 error

Hello,

I have just installed CMA 24.10.16 on Windows and configured a service to monitor a wildcard SSL certificate.

For one specific certificate, CMA appears to crash and no metrics are sent to the poller.

In the Windows Event Log, I can see the following error:

[2026-06-19 12:00:15.102] [error] [wire_format_lite.cc:610] String field 'opentelemetry.proto.metrics.v1.Metric.name' contains invalid UTF-8 data when serializing a protocol buffer. Use the 'bytes' type if you intend to send raw bytes.

The issue seems to be related to the certificate subject, which contains accented characters. The certificate CN/Subject includes:

S=Côte-d'Or, C=FR

When this certificate is checked, CMA stops sending data to the poller. Other certificates without accented characters do not appear to trigger the issue.

Could you please confirm whether this is a known issue with UTF-8 handling in CMA 24.10.16 and advise on a possible workaround or fix?

Please let me know if you need any additional logs or configuration details.

Best regards,
