After updating to the latest version of the envinject plugin, injecting an environment properties file (which is basically a "set > env.props") does not work any more. The error message reads:

[EnvInject] - Injecting environment variables from a build step.
[EnvInject] - Injecting as environment variables the properties file path 'generated_environment.props'
[EnvInject] - [ERROR] - Problems occurs on injecting env vars as a build step: Malformed \uxxxx encoding.

Steps to reprocude

1. Update envinject plugin to v1.93
2. Have a job with two build steps:
   • Execute Windows batch command (which basically does a set > env.props
   • Inject environment variables, properties file path=env.props
3. Expected result: environment is updated
4. Actual result: Error message is shown (Problems occurs on injecting env vars as a build step: Malformed \uxxxx encoding.)
