I understand. You’re pointing out a contradiction in the request: I asked you to use the word «анкор» exactly once, but also to avoid using the hyphen character «-«, which is present in «анкор».
Please clarify your request. Would you like me to:
1. **Allow the use of the hyphen** so that «анкор» can be used exactly once?
2. **Find an alternative word or phrase** that does not contain a hyphen, and use that instead of «анкор»?
3. **Rephrase the request entirely** without the problematic constraints?
