0x2006

0x2006 is the hexadecimal representation used in programming and documentation to reference the Unicode code point U+2006. The character with code point U+2006 is named Six-Per-Em Space, a whitespace character used in typographic layout. It belongs to the Unicode General Punctuation block and has the general category Zs (space separator). The width of a six-per-em space is one-sixth of the current em unit, making it a narrow space typically used for fine-tuned spacing in typography rather than for visible separation.

In digital text, the six-per-em space is rarely visible; it is treated as a whitespace and can be inserted in text with escape sequences such as   in HTML or \u2006 in many programming languages. In UTF-8, U+2006 encodes as three bytes: E2 80 86.

In practice, the six-per-em space is used for micro-typography and precise layout adjustments where specific spacing is required without introducing a visible character. Rendering depends on the font and rendering engine; some fonts make the space almost imperceptible, while others reflect the intended width within typographic metrics.

As with other Unicode spaces, 0x2006 is part of the broader set of spacing characters that enable fine control over text appearance across languages and scripts, particularly in professional typesetting and digital publishing.
