0xA0

0xA0 is a hexadecimal byte value equal to 160 in decimal. In many text encodings, including ISO-8859-1 and Windows-1252, the byte 0xA0 maps to the no-break space character, which in Unicode is U+00A0.

In Unicode, NO-BREAK SPACE (U+00A0) is categorized as a space separator (class Zs) and is intended to prevent an automatic line break at its position. It is used to keep adjacent characters together on the same line, such as in numbers, abbreviations, or certain typographic constructs.

In UTF-8, the character U+00A0 is encoded as the two-byte sequence 0xC2 0xA0. This differs from how 0xA0 appears in single-byte encodings and highlights the need to recognize the encoding in use when interpreting byte values.

In HTML and XML, the non-breaking space can be represented as the named entity   or with numeric references such as   (decimal) or   (hex). It is commonly used on webpages and in document formatting to preserve spacing where a regular space would be collapsed or allowed to wrap to a new line.

Note that 0xA0 is not part of the 7-bit ASCII standard; its interpretation depends on the encoding in use. Misinterpretation across encodings can lead to display issues, such as unintended line breaks or spacing anomalies, when moving text between systems that adopt different default encodings.
