| |  - in tinyfiledialogs, char is UTF-8 by default (since v3.6)               | |
| |                                                                            | |

| |  - for UTF-16, use the wchar_t functions at the bottom of the header file  | |
| |                                                                            | |
| |  - _wfopen() requires wchar_t                                              | |
| |  - fopen() uses char but expects ASCII or MBCS (not UTF-8)                 | |
| |  - if you want char to be MBCS: set tinyfd_winUtf8 to 0                    | |
| |                                                                            | |
| |  - alternatively, tinyfiledialogs provides                                 | |
| |                        functions to convert between UTF-8, UTF-16 and MBCS | |

- This is not for ios nor android (it works in termux though).
- The files can be renamed with extension ".cpp" as the code is 100% compatible C C++
  (just comment out << extern "C" >> in the header file)
- Windows is fully supported from XP to 10 (maybe even older versions)
- C# & LUA via dll, see files in the folder EXTRAS
- OSX supported from 10.4 to latest (maybe even older versions)
- Do not use " and ' as the dialogs will be displayed with a warning
  instead of the title, message, etc...
- There's one file filter only, it may contain several patterns.
- If no filter description is provided,
  the list of patterns will become the description.
- On windows link against Comdlg32.lib and Ole32.lib
  (on windows the no linking claim is a lie)
- On unix: it tries command line calls, so no such need (NO LINKING).
- On unix you need one of the following:
  applescript, kdialog, zenity, matedialog, shellementary, qarma, yad,
  python (2 or 3)/tkinter/python-dbus (optional), Xdialog
  or curses dialogs (opens terminal if running without console).
- One of those is already included on most (if not all) desktops.
- In the absence of those it will use gdialog, gxmessage or whiptail
  with a textinputbox. If nothing is found, it switches to basic console input,
  it opens a console if needed (requires xterm + bash).
- for curses dialogs you must set tinyfd_allowCursesDialogs=1
- You can query the type of dialog that will be used (pass "tinyfd_query" as aTitle)
- String memory is preallocated statically for all the returned values.
- File and path names are tested before return, they should be valid.
- tinyfd_forceConsole=1; at run time, forces dialogs into console mode.
- On windows, console mode only make sense for console applications.
- On windows, console mode is not implemented for wchar_T UTF-16.
- Mutiple selects are not possible in console mode.
- The package dialog must be installed to run in curses dialogs in console mode.
  It is already installed on most unix systems.
- On osx, the package dialog can be installed via
  http://macappstore.org/dialog or http://macports.org
- On windows, for curses dialogs console mode,
  dialog.exe should be copied somewhere on your executable path.
