LenChars / String Layer
Count the number of characters (Unicode code points) in each string. Similar to Python's len(str) or Rust's str.chars().count(). Counts actual characters regardless of their byte size. Useful for:
- Text length validation
- Character count limits (e.g., tweets, usernames)
- Working with multilingual text
- Display width estimation
