+    <paragraph xml-lang="en-US" role="paragraph" id="par_id381622866004346">Half-width and full-width are properties used to differentiate characters used by some East Asian languages and scripts, mainly Chinese, Japanese, and Korean (CJK).</paragraph>
+    <paragraph xml-lang="en-US" role="paragraph" id="par_id171622867006461">The Han characters, Hiragana and Katakana characters, as well as Hangul characters used by these scripts are usually of square shape, and on fixed-width (monospace) display they occupy space of two Latin/ASCII characters. They are therefore called full-width characters, while the letters in Latin alphabet, digits, and punctuation marks included in ASCII character set are called half-width characters.</paragraph>
+    <paragraph xml-lang="en-US" role="paragraph" id="par_id871622874043146">For historical reasons, a set of square-shaped Latin letters, digits, and punctuation marks are also defined and used in CJK typography, in addition to or in place of their half-width counterparts. They are called full-width forms. Similarly, there are also half-width forms of the usually full-width Katakanas and Hangul Jamos, and they have narrower shapes instead of square ones. A character's half-width and full-width forms are essentially two ways of writing the same character, just like uppercase and lowercase forms of Latin alphabet. $[officename] supports conversion between half-width and full-width, as well as ignoring width difference when matching text strings.</paragraph>
