Description

When using Telegram channel, single messages containing newline characters are being split into multiple separate messages instead of being delivered as one.

Example:

• Input: "Para entender\nmejor el patrón..."
• Expected: One message with two lines
• Actual: Two separate messages

This happens even with streamMode: "off", so it's not related to the streaming/preview feature.

Environment

• OpenClaw Version: 2.14 / 2.15
• Telegram channel
