## 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

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

bool GetClipboardContents | ( | char * | buffer,
|  | size_t | buff_len |
| ) |  |  |

Try to retrive the current clipboard contents.

Note:
  OS-specific funtion.

Returns:
  True if some text could be retrived.

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

| ) |  |  |

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
