Thread Safety

All public static members of this type are safe for multithreaded operations. No instance members are guaranteed to be thread safe.

Remarks

System.Text.UTF8Encoding encodes Unicode characters using the UTF-8 encoding (UCS Transformation Format, 8-bit form). This encoding supports all Unicode character values.

Note:

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.

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, 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 System.Globalization.UnicodeCategory .
