VB.NET Core Classes in a Nutshell

Name

UTF7Encoding

Synopsis

This class encodes Unicode characters as UTF-7, 7-bit characters. UTF-7 is a Unicode Transformation of the US-ASCII character set, designed for safe use over common Internet mail and news gateways. RFC 2152, which defines UTF-7, specifies an optional set of characters in the character set, which may or may not be encoded, because they may interfere with mail-transfer header fields. The overloaded constructor has two forms that take this into account. With no arguments, the encoding object disallows the use of optional characters (such as exclamation points and dollar signs). With a single boolean argument set to true, these optional characters are allowed in the encoding.
