What are negative circled letters?
Negative circled letters, also known as filled or inverted circle letters, are Unicode characters that display white letters on solid black circular backgrounds. These characters are part of the Enclosed Alphanumeric Supplement block (U+1F150βU+1F169) and the Dingbats block for numbers. The filled circle design creates high contrast and strong visual impact, making text appear bold and prominent. Originally designed for labeling and annotation systems, these characters have become popular for creating attention-grabbing text in digital communications. As native Unicode symbols, they display consistently across all devices and platforms.
Tool description
The Circled Filled Text Converter transforms standard text into negative circled (inverted bubble) Unicode characters and vice versa. Input like "hello world" becomes "π π π π π π ¦π π ‘π π " with each letter displayed as white on a filled black circle. The tool supports bidirectional conversionβencode normal text into filled circled format or decode it back to regular letters. Numbers convert to their dingbat equivalents (βΏβΆβ·βΈβΉβΊβ»βΌβ½βΎ). Note that this character set uses the same filled symbols for both uppercase and lowercase input, as distinct lowercase variants don't exist in Unicode.
