Function Documentation

char* convert_from_fs ( const wchar_t *  name,
char *  utf8_buf,
size_t  buflen 
)

Convert to OpenTTD's encoding from that of the environment in UNICODE.

OpenTTD encoding is UTF8, local is wide

Parameters:
name pointer to a valid string that will be converted
utf8_buf pointer to a valid buffer that will receive the converted string
buflen length in characters of the receiving buffer
Returns:
pointer to utf8_buf. If conversion fails the string is of zero-length

wchar_t* convert_to_fs ( const char *  name,
wchar_t *  utf16_buf,
size_t  buflen 
)

Convert from OpenTTD's encoding to that of the environment in UNICODE.

OpenTTD encoding is UTF8, local is wide

Parameters:
name pointer to a valid string that will be converted
utf16_buf pointer to a valid wide-char buffer that will receive the converted string
buflen length in wide characters of the receiving buffer
Returns:
pointer to utf16_buf. If conversion fails the string is of zero-length

Definition at line 1299 of file win32.cpp.

Referenced by OTTD2FS().

const char* FS2OTTD ( const TCHAR *  name  ) 

Convert to OpenTTD's encoding from that of the local environment.

When the project is built in UNICODE, the system codepage is irrelevant and the input string is wide. In ANSI mode, the string is in the local codepage which we'll convert to wide-char, and then to UTF-8. OpenTTD internal encoding is UTF8. The returned value's contents can only be guaranteed until the next call to this function. So if the value is needed for anything else, use convert_from_fs

Parameters:
name pointer to a valid string that will be converted (local, or wide)
Returns:
pointer to the converted string; if failed string is of zero-length

the current code-page comes from video\win32_v.cpp, event-notification WM_INPUTLANGCHANGE

const char* GetCurrentLocale ( const char *   ) 

Determine the current user's locale.

References lengthof.

bool InsertTextBufferClipboard ( Textbuf *  tb  ) 

Insert a chunk of text from the clipboard onto the textbuffer.

Get TEXT clipboard and append this up to the maximum length (either absolute or screenlength). If maxlength is zero, we don't care about the screenlength but only about the physical length of the string

Parameters:
tb Textbuf type to be changed
Returns:
true on successful change of Textbuf, or false otherwise

const TCHAR* OTTD2FS ( const char *  name  ) 

Convert from OpenTTD's encoding to that of the local environment.

When the project is built in UNICODE the system codepage is irrelevant and the converted string is wide. In ANSI mode, the UTF8 string is converted to multi-byte. OpenTTD internal encoding is UTF8. The returned value's contents can only be guaranteed until the next call to this function. So if the value is needed for anything else, use convert_from_fs

Parameters:
name pointer to a valid string that will be converted (UTF8)
Returns:
pointer to the converted string; if failed string is of zero-length

HRESULT OTTDSHGetFolderPath ( HWND  hwnd,
int  csidl,
HANDLE  hToken,
DWORD  dwFlags,
LPTSTR  pszPath 
)

Our very own SHGetFolderPath function for support of windows operating systems that don't have this function (eg Win9x, etc.

). We try using the native function, and if that doesn't exist we will try a more crude approach of environment variables and hope for the best
