The Agno CLI command `agno connect` adds your AgentOS to local MCP clients by editing their config files, and it now uses UTF-8 for every one of them, Codex's TOML config included. It used the operating system's default encoding for those files. On a system whose default isn't UTF-8, such as many Windows setups, a config with non-ASCII text could fail to read or end up in the wrong encoding.

Writes are still atomic and keep the file's permissions.
