## Description

ANSI Viewer is a specialized Chrome extension that allows users to seamlessly view .ans files directly in their browser. Featuring built-in support for Big5-UAO encoding, it ensures accurate rendering of text from sources like BBSFox. The extension supports rich ANSI colors, dual-color text, blinking effects, and PTT-style coloring themes, enhancing readability and user interaction. A handy keyboard shortcut (Alt + L) toggles text highlighting for quick emphasis. Ideal for users who want to view ANSI art or text files without leaving their browsing environment, ANSI Viewer brings a robust, user-friendly experience tailored to legacy text formats.
