//! Default text processor for standard file types.
//!
//! This processor handles all file types that don't require special processing.
//! It converts raw bytes to UTF-8 strings using lossy conversion to handle
//! invalid UTF-8 sequences gracefully.

use anyhow::Result;

/// Default processor that converts bytes to UTF-8 string.
///
/// This processor uses the `chardetng` crate to detect the encoding of the input bytes
/// and converts them to a UTF-8 string. If the encoding cannot be determined, it
/// defaults to UTF-8. Invalid sequences are replaced with the Unicode replacement character.
