Claude Code sets the terminal title (via escape sequences) to a conversation summary, which is useful for tmux automatic-rename-format '#{pane_title}' to show meaningful window names.

However, the title is always generated in English, even when the entire conversation is in another language (e.g., Traditional Chinese / 繁體中文).

Root Cause

Claude Code sets the terminal title (via escape sequences) to a conversation summary, which is useful for tmux automatic-rename-format '#{pane_title}' to show meaningful window names.

However, the title is always generated in English, even when the entire conversation is in another language (e.g., Traditional Chinese / 繁體中文).

Code Example

# tmux window list currently shows:
1:Update chat conversation layout
2:Database domain field investigation
3:Customize Moshi shortcuts and command order

# Would be more useful as:
1: ✳ 更新聊天對話版面
2: ✳ 資料庫 domain 欄位調查
3: ⠐ 自訂 Moshi 捷徑與命令排序

Description

Claude Code sets the terminal title (via escape sequences) to a conversation summary, which is useful for tmux automatic-rename-format '#{pane_title}' to show meaningful window names.

However, the title is always generated in English, even when the entire conversation is in another language (e.g., Traditional Chinese / 繁體中文).

Current behavior

Conversation in Chinese → terminal title: ✳ Customize Moshi shortcuts and command order

Expected behavior

Conversation in Chinese → terminal title: ✳ 自訂 Moshi 捷徑與命令排序

The title language should match the conversation language.

Context

This matters for developers who use tmux with automatic-rename-format '#{pane_title}' to manage multiple Claude Code sessions. When all titles are in English but the work is in another language, the mental mapping breaks.

# tmux window list currently shows:
1: ✳ Update chat conversation layout
2: ✳ Database domain field investigation
3: ⠐ Customize Moshi shortcuts and command order

# Would be more useful as:
1: ✳ 更新聊天對話版面
2: ✳ 資料庫 domain 欄位調查
3: ⠐ 自訂 Moshi 捷徑與命令排序

Environment

  • Claude Code 2.1.96
  • tmux 3.4
  • Ubuntu 24.04

extent analysis

TL;DR

The terminal title should be translated to match the conversation language, which can be achieved by modifying the title generation logic in Claude Code to support multiple languages.

Guidance

  • Investigate the title generation logic in Claude Code to identify where the English title is being set and determine if there's an existing mechanism for internationalization (i18n) or localization (L10n).
  • Consider using a translation library or service to generate titles in the correct language based on the conversation content.
  • Review the automatic-rename-format setting in tmux to ensure it's correctly configured to display the pane title.
  • Check if Claude Code provides any configuration options or APIs for customizing the title generation process.

Example

No specific code example can be provided without more information about the Claude Code internals, but a potential approach might involve using a translation library to generate the title:

import translate

def generate_title(conversation):
    # Determine the conversation language
    language = detect_language(conversation)
    # Generate the title using a translation library
    title = translate.translate("Customize Moshi shortcuts and command order", language)
    return title

Notes

The solution will depend on the specifics of the Claude Code implementation and the available translation mechanisms. This guidance provides a general direction, but a more detailed investigation of the code and its configuration options is necessary.

Recommendation

Apply a workaround by modifying the title generation logic in Claude Code to support multiple languages, as upgrading to a fixed version is not mentioned as an option. This approach allows for a more tailored solution to the specific language support requirements.
