[BUG] Cannot type "@"

Environment

• Platform (select one):
• [x ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 0.2.94 (Claude Code)
• Operating System: Version 15.3.1 (24D70)
• Terminal: Warp (https://www.warp.dev/)

Bug Description

I cannot enter the symbol "@" (or "~", potentially others) when using Claude Code.

Steps to Reproduce

1. Open Claude Code in Warp
2. Attempt to enter "@" by using the keyboard.

Expected Behavior

@ appears

Actual Behavior

@ does not appear

Additional Context

• I'm able to enter @ in Warp outside of Claude Code
• I'm able to enter @ in Claude Code using the default macOS Terminal

Given the above, I'm not sure if this is an issue with Warp or Claude Code. Please advise, if I should instead file a bug report with Warp.

• The issue appears using the German keyboard layout (@ = option + L). Using a US keyboard layout (@ = Shift + 2), I'm able to enter the symbol.
• I'm able to copy + paste the symbol into Claude Code.
• Being able to conveniently type "@" is important to use the (new) feature of tagging files into context.
