SYMPTOMS

Consider the following scenario:
  • You create a Visual C++ project in Microsoft Visual Studio 2008 Service Pack 1 (SP1).
  • A file in the project has narrow string literals. These string literals contain Asian characters and are not prefixed with the letter "L."
  • The string literals use UTF-8 encoding.
In this scenario, when you compile the project, the string literals are misinterpreted by the compiler. Additionally, you encounter one of the following issues:
  • The compile operation succeeds. However, the string literals are displayed incorrectly in the generated application. Additionally, you may also receive the following warning messages when you compile the project:
    warning C4566: character represented by universal-character-name 'xx’ cannot be represented in the current code page.
  • The compile operation fails. Additionally, you may receive the following error message when you compile the project:
    error C2078: too many initializers

CAUSE

This problem occurs because the compiler assumes that the file in the "Symptoms" section has MBCS encoding. Because of this behavior, the compilerincorrectly translates the file.

MORE INFORMATION

To resolve the error in compiler, install this hotfix and then save the file together with a byte-order mark. Additionally, add the following "pragma" directive just before the string literals in the source file.

#pragma execution_character_set("utf-8")
Note The "pragma" directive sets the translation unit for the source file until the "pragma" directive is replaced by another "pragma" directive.
