[BUG] UnicodeDecodeError when inheriting Gradio components on Windows

[Lee-Ju-Yeong]

Description

When inheriting from Gradio's gr.File component to create a new component, a UnicodeDecodeError occurs on Windows due to 'cp949' codec issues. This happens because Gradio's internal code uses the default system encoding when reading files.

Reproduction steps

# optional (setup env)
conda create -n kotaemon python=3.10
conda activate kotaemon

pip install -e "libs/kotaemon[all]"
pip install -e "libs/ktem"
