How is one to tell the difference, in Pythonscript, if the current file’s encoding is UTF-8 without BOM, or for example, ISO-8859-1 ?

I thought there would be a way to read back the character set, distinct from the GETBUFFERENCODING message… but I cannot find a message that does that. Barring that, I thought that the scintilla object might have that info somewhere, but I cannot find it there, either. …maybe @Ekopalypse has insight on this one.

Sorry, but I have no idea.
So…it’s a bit cheesy, but one can read the status bar field that shows the encoding type to get this information (as its text string).
We’ve discussed in this forum how to get the status bar data before using a PythonScript, but I’ve revamped my code for doing it so I’ll post the whole thing here.
Here’s NotepadGetStatusBar.py with a demo at the end to show the current file’s encoding:
# -*- coding: utf-8 -*- from __future__ import print_function from Npp import * import ctypes from ctypes.wintypes import BOOL, HWND, WPARAM, LPARAM, UINT class NGSB(object): # implements a "getStatusBar" function (complement to notepad.setStatusBar()) def __init__(self): self.SendMessageW = ctypes.windll.user32.SendMessageW LRESULT = LPARAM self.SendMessageW.restype = LRESULT self.SendMessageW.argtypes = [ HWND, UINT, WPARAM, LPARAM ] self.create_unicode_buffer = ctypes.create_unicode_buffer self.curr_class_256 = self.create_unicode_buffer(256) self.STATUSBAR_HANDLE = None self._determine_statusbar_handle() assert self.STATUSBAR_HANDLE def get_statusbar_by_section(self, statusbar_item_number): # statusbar_item_number can be integer 0 thru 5 or one of: # STATUSBARSECTION.DOCTYPE # STATUSBARSECTION.DOCSIZE # STATUSBARSECTION.CURPOS # STATUSBARSECTION.EOFFORMAT # STATUSBARSECTION.UNICODETYPE # STATUSBARSECTION.TYPINGMODE return self._get_statusbar_section(statusbar_item_number) def get_statusbar_as_tuple(self): section_list = [ STATUSBARSECTION.DOCTYPE, STATUSBARSECTION.DOCSIZE, STATUSBARSECTION.CURPOS, STATUSBARSECTION.EOFFORMAT, STATUSBARSECTION.UNICODETYPE, STATUSBARSECTION.TYPINGMODE, ] return tuple(list(map(lambda x: self._get_statusbar_section(x), section_list))) def _determine_statusbar_handle(self): WNDENUMPROC = ctypes.WINFUNCTYPE(BOOL, HWND, LPARAM) FindWindowW = ctypes.windll.user32.FindWindowW FindWindowExW = ctypes.windll.user32.FindWindowExW EnumChildWindows = ctypes.windll.user32.EnumChildWindows GetClassNameW = ctypes.windll.user32.GetClassNameW self.STATUSBAR_HANDLE = None def enum_callback_fn(hwnd, lparam): GetClassNameW(hwnd, self.curr_class_256, 256) if self.curr_class_256.value.lower() == "msctls_statusbar32": self.STATUSBAR_HANDLE = hwnd return False # stop the enumeration return True # continue the enumeration npp_hwnd = FindWindowW(u"Notepad++", None) #print('npp_hwnd:', npp_hwnd) EnumChildWindows(npp_hwnd, WNDENUMPROC(enum_callback_fn), 0) #print('self.STATUSBAR_HANDLE:', self.STATUSBAR_HANDLE) def _get_statusbar_section(self, statusbar_item_number): assert statusbar_item_number <= 5 WM_USER = 0x400 SB_GETTEXTLENGTHW = WM_USER + 12 SB_GETTEXTW = WM_USER + 13 SBT_OWNERDRAW = 0x1000 retcode = self.SendMessageW(self.STATUSBAR_HANDLE, SB_GETTEXTLENGTHW, statusbar_item_number, 0) length = retcode & 0xFFFF type = (retcode >> 16) & 0xFFFF assert (type != SBT_OWNERDRAW) text_buffer = self.create_unicode_buffer(length) retcode = self.SendMessageW(self.STATUSBAR_HANDLE, SB_GETTEXTW, statusbar_item_number, ctypes.addressof(text_buffer)) retval = '{}'.format(text_buffer[:length]) return retval if __name__ == '__main__': print(NGSB().get_statusbar_by_section(STATUSBARSECTION.UNICODETYPE))Running the script will print the current file’s encoding (from statusbar information) to the Pythonscript console window.
