Unexpected symbol: '^' (0x5e)

[a-hansen]

The following is happening in version 3.0.5, against SkySpark 3.0.26. My customer is reporting that one of the tags equals or contains the '^' char. Is this a problem with this lib, or some sort of version incompatibility?

We need to add Symbol kind support to the library. The ^ is used to encode a ^symbol
