Encoding issue

[redhead]

If I have a json AST file in utf-8 encoding with Czech special characters (e.g. ščřž) the output of matter_compiler has some wierd characters probably as a result of not handling the encoding properly:

"name": "Integrační portál",
"resourceGroups": [
    {
        "name": "Uživatelé",
        "description": "API pro administraci uživatelů.\n\n",

output

# Integra─Źn├ş port├íl
# Group U┼żivatel├ę
API pro administraci u┼żivatel┼».
