International Character Sets support in .NET communications controls refers to the ability of networking and messaging components to correctly transmit, receive, and process text data encoded in various global character standards, such as Unicode, UTF-8, UTF-16, and legacy code pages. This capability ensures that applications can reliably handle multilingual content, including non-Latin scripts, accented characters, symbols, and right-to-left languages, without data corruption or misinterpretation during serialization, transport, or display. By supporting standardized encoding mechanisms, .NET communications controls allow developers to build globally compatible services, APIs, email clients, and messaging systems that maintain text integrity across different platforms, operating systems, and regional settings, which is essential for modern distributed and internationalized applications.
Several .NET communications and messaging components offer support for international character sets including:

TLS support in an internet component refers to the implementation of Transport Layer Security, a protocol that encrypts data exchanged between systems over a network. For software developers, this ensures that data sent and received by the component is protected against eavesdropping, tampering, and forgery, which is essential for maintaining secure communications in modern applications. By using TLS, developers can meet compliance requirements, safeguard user information, and build trust in the integrity of their applications' network interactions.
Several Comms & Messaging components for .NET offer TLS support including:
