wch

WCH is an acronym and code that can refer to several different things depending on context. There is no single authoritative meaning for "wch." In sports and competitive events, WCh is a common abbreviation for World Championship, used across many disciplines to denote the world-title competition. In chess literature the form WCh is often used to indicate the World Chess Championship specifically.

In medicine and healthcare contexts, WCH is frequently the English-language abbreviation for West China Hospital, a major teaching hospital associated with Sichuan University.

In computing and software development, "wch" or "WCH" may appear as shorthand for "wide character" in discussions of character encoding and string handling. Programming examples and naming conventions sometimes use "wch" as a variable or function prefix to indicate wide-character processing, for example when dealing with wchar_t or Unicode strings. The exact interpretation depends on the codebase and documentation.

Other uses are rare and highly context-dependent. WCH can appear as an organizational acronym, facility name, or project code in various institutions, and should be interpreted from surrounding text.
