# Context:
USER: Add a read_text function to the InputOutput class. It takes the file name as argument, and returns the text for that file. Internally, if we get a Unicode error or a FileNotFound error, it prints ToolErrorOutput to notify the user, and then returns None. Add a command-line switch, and dash-dash encoding, which defaults to UTF-8. That's the encoding which will be used by the read_text function.
ASSISTANT: To implement the requested changes, we need to modify the following files:
1. `aider/io.py`: To add the `read_text` function to the `InputOutput` class.
2. `aider/main.py`: To add the `--encoding` command-line switch.
Let's start with the changes to `aider/io.py`:
```python
aider/io.py
<<<<<<< ORIGINAL
class InputOutput:
num_error_outputs = 0
num_user_asks = 0
def __init__(
self,
pretty=True,
yes=False,
input_history_file=None,
chat_history_file=None,
input=None,
output=None,
user_input_color="blue",
tool_output_color=None,
tool_error_color="red",
):
no_color = os.environ.get("NO_COLOR")
if no_color is not None and no_color != "":
pretty = False
self.user_input_color = user_input_color if pretty else None
self.tool_output_color = tool_output_color if pretty else None
self.tool_error_color = tool_error_color if pretty else None
self.input = input
self.output = output
self.pretty = pretty
if self.output:
self.pretty = False
self.yes = yes
self.input_history_file = input_history_file
if chat_history_file is not None:
self.chat_history_file = Path(chat_history_file)
else:
self.chat_history_file = None
if pretty:
self.console = Console()
else:
self.console = Console(force_terminal=False, no_color=True)
current_time = datetime.now().strftime("%Y-%m-%d %H:%M:%S")
self.append_chat_history(f"\n# aider chat started at {current_time}\n\n")

return f.read()

return None

```
Now, let's add the `--encoding` command-line switch to `aider/main.py`:
```python
aider/main.py
<<<<<<< ORIGINAL
parser.add_argument(
"--no-dirty-commits",
action="store_false",
dest="dirty_commits",
help="Disable commits when repo is found dirty",
)

metavar="OPENAI_API_KEY",

)
parser.add_argument(
"--openai-api-base",
metavar="OPENAI_API_BASE",
default="https://api.openai.com/v1",
help="Specify the OpenAI API base endpoint (default: https://api.openai.com/v1)",
)

These changes should implement the requested functionality. Please review and let me know if any further changes are needed.
The source code output in the chat will be colored in the given
color scheme. Syntax highlighting is powered by pygments, which
supports many styles out of the box. For example:
- default (the default)
- dracula
- emacs
- github-dark
- monokai
- vim
