The goal was to include all required characters from most of the world's languages, as well as symbols from technical domains such as science, mathematics, and music. The original idea was to replace the typical 256-character encodings, which required 1 byte per character, with an encoding using 65,536 (2<sup>16</sup>) values, which would require 2 bytes (16 bits) per character. </p><p>Two groups worked on this in parallel, <a href="/wiki/ISO/IEC_JTC_1/SC_2" title="ISO/IEC JTC 1/SC 2">ISO/IEC JTC 1/SC 2</a> and the <a href="/wiki/Unicode_Consortium" title="Unicode Consortium">Unicode Consortium</a>, the latter representing mostly manufacturers of computing equipment.

This simplifies searches a great deal. It also means that UTF-16 is <i><a href="/wiki/Self-synchronizing_code" title="Self-synchronizing code">self-synchronizing</a></i> on 16-bit words: whether a code unit starts a character can be determined without examining earlier code units (i.e. the type of <i>code unit</i> can be determined by the ranges of values in which it falls). UTF-8 shares these advantages, but many earlier multi-byte encoding schemes (such as <a href="/wiki/Shift_JIS" title="Shift JIS">Shift JIS</a> and other Asian multi-byte encodings) did not allow unambiguous searching and could only be synchronized by re-parsing from the start of the string. UTF-16 is not self-synchronizing if one byte is lost or if traversal starts at a random byte. </p><p>Because the most commonly used characters are all in the BMP, handling of surrogate pairs is often not thoroughly tested. This leads to persistent bugs and potential security holes, even in popular and well-reviewed application software (e.g. <a href="/wiki/CVE_(identifier)" class="mw-redirect" title="CVE

In practice, due to Windows using little-endian (LE) order by default, many applications assume little-endian encoding. It is also reliable to detect endianness by looking for null bytes, on the assumption that characters less than U+0100 are very common. If more even bytes (starting at 0) are null, then it is big-endian. </p><p>The standard also allows the byte order to be stated explicitly by specifying <b>UTF-16BE</b> or <b>UTF-16LE</b> as the encoding type.
