The following example of a message loop (modified slightlyįrom Borland Delphi’s forms.pas) may be useful in helping you to support having You can create a window as Unicode (even in a generally ANSIĪpplication) by ensuring that you use the following functions instead of the Unicode input in Windows NT4, 2000, XP, Vista and 7 Thing it cannot do is allow windows to be created as Unicode – so direct Unicode functionality to Windows 9x through a library. MSLU – Microsoft Layer for Unicode – provides missing Will tell you whether the window supports Unicode input. Will contain Unicode (UTF-16) characters. If the window is created as a Unicode window, all WM_CHAR messages Window, WM_CHAR will always be received by the window class as codepageĬharacters. Windows, in Windows NT4, 2000, XP, Vista or 7. In particular, windows can created either as ANSI or Unicode This means that if you didn’t create your application in the last 2 or 3 years, it is quite likely that it does not support Unicode input. Many application development frameworks originally did not support the Unicode functions. Many applications have been created using ANSIįunctions as the Unicode functions were not supported (apart from a few specialĮxceptions) under Windows 95, 98 and Me. The ANSI functions work in 8-bit land, supporting only codepage based input. GetWindowText maps to either GetWindowTextA or GetWindowTextW, depending on the flags with which your application is compiled. (ANSI) and the "W" (Wide or Unicode) functions. Windows has two classes of functions: the "A" It is perhaps less important now than it was 5 years ago, but it is still helpful for those poor souls among us who are tasked with looking after existing legacy applications!
