A character that shows up as three garbled symbols instead of one accented letter is usually a UTF-8 byte sequence read as something else entirely, and tracking that down means understanding several encoding layers at once, how a character maps to raw bytes, how those bytes might get represented as Base64, how a reserved character gets percent-encoded in a URL, rather than consulting a separate page for each one. This tool provides reference tables covering ASCII, UTF-8, HTML entities, URL encoding, Base64, and more, built as a single cross-reference rather than several separate lookup pages.

Useful for tracking down an encoding mismatch bug by checking how a character is represented across several layers at once, looking up a Base64 or percent-encoded value's meaning without switching between reference sites, or understanding how a character moves from its raw byte representation through to a URL-safe or HTML-safe form.

Quick answers for Encodings Reference

What encoding tables does it include?

Four reference tables: ASCII characters 32 to 126 with decimal and hex codes, common HTML entities in named and numeric form, URL-encoded special characters, and the full Base64 alphabet with its padding character.

Can I search within a table instead of scrolling?

Yes, a live search box filters whichever table tab is active, matching against the character, its name, or its code.

Does it encode text I type in?

No, it's a static lookup reference for the tables themselves rather than an encoder for arbitrary input.
