No. I don’t think anybody generally expects log message parameterization to do anything like escaping or white space normalization or anything to the parameters that wouldn’t also be done to the message string.

If you are using a logger to output a message which you want to be able to parse based on delimiters, say, it would be up to you to escape any parameters you were incorporating into it to ensure they don’t confuse your parser.
