What's wrong with that?

It's not the first non-ASCII character in the source code, not even the first in a public header.

We have a whitelist of Unicode characters that includes diacritics over Latin characters for bibliographical references and some common punctuation and mathematical characters.

Best regards,

Hi Stephan,

Thank you for spotting that. That is not intended and will be looked into.

Hello Mbed TLS team,

Mbed TLS 3.6 introduced the first UTF-8 characters “±” in source code, see mbedtls_config.h, line 4179:

* at the same pace. The typical accuracy of an RTC crystal is ±100 to ±20 parts

Is this intended?

Thanks

Stephan
