SYMPTOMS
No text appears after a double-byte character set (DBCS) character is written to a file.

For instance, in the following code snippet, the text &quot; There&quot; is not written to the STLout.txt file after the DBCS character 0x30F0 is written to a file.
 * 1) include

void main { wchar_t ch = 0x30F0; /* DBCS Japanese test character. */  std::wofstream wfout; wfout.imbue(std::locale(&quot;Japanese&quot;)); wfout.open(&quot;STLout.txt&quot;); wfout << L&quot;Hello&quot;; wfout << ch; /* Write the DBCS character to the output text file. */  //wfout.clear; /* Workaround: Call clear after the DBCS output. */  wfout << L&quot; There\n&quot;;  /* This is not written to the output text file. */ }
