This article addresses encoding problems that arise when using CSS pseudo-elements to insert special characters (such as bullets) in email stationery. When CSS styles are rendered in email clients, special characters like "■" or "•" may be incorrectly converted to HTML entities (e.g., "&#adabacadabra;"), leading to display anomalies. By analyzing the root causes, the article proposes using Unicode code points (e.g., content: '\2022') as a solution to ensure correct character display across various email clients. It details the syntax of Unicode notation in CSS, compares hexadecimal and decimal encodings, and discusses the peculiarities of character encoding in email environments. Additionally, it briefly mentions alternative approaches, such as avoiding CSS pseudo-elements or using image replacements. Aimed at front-end developers and email designers, this article provides practical technical guidance for achieving consistent bullet rendering in cross-platform email designs.
