[Bug] Special characters (accents/unicode) not displaying correctly in PowerShell on Windows after v2.0.73 update

Description

After updating to Claude Code v2.0.73, special characters (accented letters like a, e, c, a, etc.) are not displaying correctly in PowerShell on Windows. Characters appear as broken/missing symbols.

Environment

• Claude Code version: 2.0.73
• OS: Windows
• Terminal: PowerShell
• Language: Portuguese (but likely affects all non-ASCII characters)

Steps to Reproduce

1. Update Claude Code to version 2.0.73
2. Run claude in PowerShell
3. Ask a question that generates a response with accented characters
4. Observe that special characters are not rendered correctly

Expected Behavior

Special characters (a, e, i, o, u, a, o, c, etc.) should display correctly as they did in previous versions.

Actual Behavior

Special characters appear as broken symbols or do not appear at all.

Workaround

Setting UTF-8 encoding in PowerShell does not fix the issue:

• [Console]::OutputEncoding = [System.Text.Encoding]::UTF8
• chcp 65001

Additional Context

This issue started specifically after updating to v2.0.73. Previous versions worked correctly.
