claude-code - 💡(How to fix) Fix [BUG] Japanese (CJK) characters garbled during streaming output [1 comments, 2 participants]

TL;DR

The issue with garbled Japanese characters in Claude Code's streaming output may be resolved by adjusting the tokenization or encoding handling for CJK characters.

Guidance

• Verify that the issue is not related to the terminal emulator or shell by testing with different setups, as the user has already done.
• Investigate the tokenization process in Claude Code to see if it's splitting CJK characters incorrectly, potentially causing the corruption.
• Check the encoding settings in Claude Code and the environment to ensure that UTF-8 is properly supported and handled.
• Consider testing with a different locale or character set to isolate if the issue is specific to Japanese characters or a more general problem.

Example

No specific code example can be provided without more details on Claude Code's internal workings, but checking the encoding and tokenization handling in the codebase may look something like reviewing character encoding settings or tokenization algorithms for proper handling of multi-byte characters.

Notes

The issue seems to be related to how Claude Code handles CJK characters during streaming output, possibly due to incorrect tokenization or encoding. However, without access to the codebase or more specific details on how Claude Code processes text, it's challenging to provide a precise fix.

Recommendation

Apply a workaround by adjusting the character encoding or tokenization settings in Claude Code, if possible, to better handle CJK characters until a more permanent fix can be implemented. This approach is recommended because it directly addresses the likely cause of the issue and can provide a temporary solution for users experiencing the problem.
