# Windows code page identifier (`windows_code_page`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Number of a character encoding in Windows, as in 1251 for Windows Cyrillic and 65001 for UTF-8. Identifiers run from 037 to 65001. File metadata, database collations and the chcp command use them. The name of the encoding is a separate record (character_encoding). Any number of three to five digits matches, so use the field name or context.
