Generated Ion file contains non UTF-8 characters?

[ssomayyajula]

Following the instructions for generating the Python dialect, I'm able to successfully run python -m strata.gen dialect dialect_dir. However, when I run the following command:

lake exe StrataVerify --check Tools/Python/dialect_dir/Python.dialect.st.ion

I get:

uncaught exception: Tried to read file 'Tools/Python/dialect_dir/Python.dialect.st.ion' containing non UTF-8 data.

Starting a discussion here rather than creating an issue, as I'm not sure whether this is an actual bug or that I haven't followed the instructions correctly.
