      <para>
        <see cref="T:System.Text.UTF8Encoding" />
encodes Unicode characters
using the UTF-8 encoding (UCS Transformation Format, 8-bit form). This encoding supports
all Unicode character values.</para>
      <block subset="none" type="note">
        <para>UTF-8 encodes Unicode characters with a variable number of bytes per
      character. This encoding is optimized for the lower 127 ASCII characters,
      yielding an efficient mechanism to encode English in an internationalizable way.
      The UTF-8 identifier is the Unicode byte order mark (0xFEFF) written in UTF-8
      (0xEF 0xBB 0xBF). The byte order mark is used to distinguish UTF-8 text from
      other encodings.</para>
        <para>This class offers an error-checking feature that can be
      turned on when an instance of the class is constructed. Certain methods in this
      class check for invalid sequences of surrogate pairs. If error-checking is
      turned on and an invalid sequence is detected, <see cref="T:System.ArgumentException" /> is
      thrown. If error-checking is not turned on and an invalid sequence is
      detected, no exception is thrown and execution continues in a method-defined
      manner. For more information regarding surrogate pairs, see <see cref="T:System.Globalization.UnicodeCategory" />
