[BUG] [Windows only] Table defaults to safe_box when the output is piped.

[zapta]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

When running on window and with piped output, the table are displayed in "safe box" mode by default. This is not the case on Max OSX and Linux.

Run this on windows and pipe the output.

from rich.console import Console
from rich.table import Table
from rich import box

console = Console(color_system="auto", force_terminal=True)

table = Table(
  show_header=True,
  show_lines=True,
  box=box.SQUARE,
  border_style="dim",
  title="My Table")

table.add_column("COL1")
table.add_column("COL2")

table.add_row("aaa", "bbb", style="red")
table.add_row("ccc", "ddd")

console.print(table)

Workaround: Add this at the beginning of the program:

sys.stdout.reconfigure(encoding='utf-8')

Platform

What platform (Win/Linux/Mac) are you running on? What terminal software are you using?

Windows 10. (it's ok on Mac and Linux). Reproduced on both windows cmd and on git bash.
