补充， 我最开始用的是kimi 1.5 用的很好，
后来升级到kimi 1.6 就出现这个问题， 完全无法使用
我又降级回1.5 依然无法使用

In addition, I first used kimi 1.5 and it worked very well.
After upgrading to kimi 1.6, this problem occurred and it was completely unusable.
I downgraded back to 1.5 and still can't use it.

首次购买kimi-cli，在deepin-terminal和terminator两个终端模拟器中都遇到相同的问题。

rm -rf ~/.kimi/sessions/*
尝试一下这个
根本原因：
Session 文件中包含单独的 surrogate 字符（U+D800-U+DFFF）
Context 恢复时读取了这些损坏的数据
发送 HTTP 请求时，json.dumps(ensure_ascii=False) 保留了 surrogate
httpx 尝试 .encode('utf-8') 时失败

[ecjtusbs]

kimi 1.26.0 存在同样的问题。

环境： deepin v25版本
终端模拟器： Terminator
LANG = zh_CN.UTF-8
LC_ALL = [空]

[ecjtusbs]

如下方式解决：

➜ ~ python3 --version
Python 3.12.11

找到 system.md 文件

SYSTEM_FILE="$HOME/.local/share/uv/tools/kimi-cli/lib/python3.13/site-packages/kimi_cli/agents/default/system.md"

备份原文件

cp "$SYSTEM_FILE" "$SYSTEM_FILE.bak"

使用 iconv 清理非法字符

iconv -f UTF-8 -t UTF-8//IGNORE "$SYSTEM_FILE.bak" > "$SYSTEM_FILE"

或者用 Python 清理

python3 -c "
import sys
with open('$SYSTEM_FILE', 'r', encoding='utf-8', errors='ignore') as f:
content = f.read()
with open('$SYSTEM_FILE', 'w', encoding='utf-8') as f:
f.write(content)
"
