This bug was discussed and solved here: ​https://www.autoitscript.com/forum/topic/188643-is-_guictrlrichedit_streamtovar-limited-to-2048-chars/

The problem happens when trying to stream a RichEdit with length > 2048 to a variable with _GUICtrlRichEdit_StreamToVar. The stream to file works correctly in this matter. The problem lies within this code which is called by the function:

Func __GCR_StreamToVarCallback($iCookie, $pBuf, $iBuflen, $pQbytes)
	#forceref $iCookie
	Local $tQbytes = DllStructCreate("long", $pQbytes)
	DllStructSetData($tQbytes, 1, 0)
	Local $tBuf = DllStructCreate("char[" & $iBuflen & "]", $pBuf)
	Local $s = DllStructGetData($tBuf, 1)
	$__g_pGRC_sStreamVar &= $s
	Return 0
EndFunc   ;==>__GCR_StreamToVarCallback

The buffer is not updated correctly at the end of the function. The solution is to add a line before the return statement and modify the earlier struct set:

Func __GCR_StreamToVarCallback($iCookie, $pBuf, $iBuflen, $pQbytes)
	#forceref $iCookie
	Local $tQbytes = DllStructCreate("long", $pQbytes)
	DllStructSetData($tQbytes, 1, $iBuflen) ;Modified this line
	Local $tBuf = DllStructCreate("char[" & $iBuflen & "]", $pBuf)
	Local $s = DllStructGetData($tBuf, 1)
	$__g_pGRC_sStreamVar &= $s
	DllStructSetData($tQbytes, 1, StringLen($s)) ;Added this line
	Return 0
EndFunc   ;==>__GCR_StreamToVarCallback

This correctly updates the struct and solves the character limit.

There's an old feature request #15 about fixing the various limitations of the Ini functions (what's not mentioned there is that they sometimes throw an @error when their target is called Autoinf.inf).

But I have a different feature request - just document the fact that there are limitations, to avoid confusion.

Do functions like FileRead not suffer from such limitations because they are custom made by AutoIt, while Ini functions use Windows API? If so, mention this officially. For example:

IniReadSectionNames

Remarks
Note that Ini functions rely on Windows API which suffers from various limitations.
This situation shall remain as Microsoft asked to use other storage methods.
Custom UDFs that bypass the limitations can be found on AutoIt's forums.

Now _SQLite_Startup() prohibit use dll without "_x64" in dll name in 64 bit script. It not very convenient.

Func _SQLite_StartupEX($sDll_Filename = "", $bUTF8ErrorMsg = False, $iForceLocal = 0, $hPrintCallback = $__g_hPrintCallback_SQLite)
	#forceref $iForceLocal
	If $sDll_Filename = Default Or $sDll_Filename = -1 Then $sDll_Filename = ""

	If $hPrintCallback = Default Then $hPrintCallback = __SQLite_ConsoleWrite
	$__g_hPrintCallback_SQLite = $hPrintCallback

	If $bUTF8ErrorMsg = Default Then $bUTF8ErrorMsg = False
	$__g_bUTF8ErrorMsg_SQLite = $bUTF8ErrorMsg

	If $sDll_Filename = "" Then $sDll_Filename = "sqlite3.dll"

	Local $hDll = DllOpen($sDll_Filename)
	If $hDll = -1 Then
		$__g_hDll_SQLite = 0
		Return SetError(1, 0, "")
	Else
		$__g_hDll_SQLite = $hDll
		Return SetExtended(0, $sDll_Filename)
	EndIf
EndFunc   ;==>_SQLite_Startup
