Summary

Telegram channel incorrectly treats "|" pipe character as spoiler/hidden text

Steps to reproduce

1. Send any message from assistant that contains "|" character (e.g., emoticons like "(￣_￣|)" or text with pipe separators)
2. View the message in Telegram client
3. Observe that text after "|" appears as spoiler (gray hidden block)

Expected behavior

The "|" character should be displayed as plain text. Only actual Telegram spoiler syntax "||text||" should create spoilers.

Actual behavior

Text after a single "|" is sometimes rendered as spoiler (hidden/grayed out).
See screenshot - "123123" appears as gray dots after the pipe character.
Note: This bug appears intermittently and may depend on message context/length.
