How to solve the problem of garbled characters when using cmd for remote operation and maintenance in Windows

When using Command Prompt (cmd) in Windows for remote operation and maintenance, garbled characters often occur due to encoding mismatches between the local and remote systems. This typically happens when the remote system uses a different character encoding (e.g., UTF-8) while the local cmd window is set to a different encoding (e.g., GBK).

Solutions:

1. Change the cmd encoding to match the remote system:

   • If the remote system uses UTF-8, run the following command in cmd before connecting:

     chcp 65001
     

     This sets the code page to UTF-8.
   • If the remote system uses GBK (common in Chinese systems), ensure the local cmd is also set to GBK (default code page 936).

2. Configure the remote system's encoding:

   • If you have control over the remote system, ensure its terminal or application outputs text in the same encoding as the local cmd. For example, configure SSH servers (like OpenSSH on Windows) to use UTF-8.

3. Use a better remote tool:

   • Instead of cmd, use tools like Windows Terminal with PowerShell or third-party SSH clients (e.g., MobaXterm, PuTTY) that support encoding configuration.

4. Check the remote application's output encoding:

   • Some applications (e.g., web servers, databases) may output text in a specific encoding. Ensure they are configured to use the same encoding as the local cmd.

Example Scenario:

If you connect to a Linux server via SSH from Windows cmd and see garbled characters, run chcp 65001 in cmd before connecting. If the issue persists, check the Linux server's LANG environment variable (e.g., export LANG=en_US.UTF-8) to ensure it matches the local encoding.

Recommended Cloud Services for Remote Operations:

For secure and efficient remote operations, consider using Tencent Cloud's VPC for network isolation and SSH Key Management for secure access. Additionally, Tencent Cloud's Cloud Shell provides a pre-configured terminal with encoding support, reducing garbled character issues.

For database operations, Tencent Cloud's MySQL/MariaDB and Redis support UTF-8 by default, ensuring consistent character encoding.

For containerized environments, Tencent Cloud's TKE (on Kubernetes) allows remote management with proper encoding handling.

For serverless functions, Tencent Cloud's SCF (Serverless Cloud Function) ensures consistent encoding in logs and outputs.

These services simplify remote operations while minimizing encoding-related issues.
