[Done] ~"\t" Doesn't work in VectorDrawing, Windows 10

The following code works as expected on Mac OSX but not on Windows.

Tested on Windows 10 with PureBasic 5.50 64 bit and PureBasic 5.51 64 bit.

Code:

EnableExplicit

  CompilerIf #PB_Compiler_Unicode
    #XmlEncoding = #PB_UTF8
  CompilerElse 
    #XmlEncoding = #PB_Ascii
  CompilerEndIf

  #Dialog = 0
  #Xml = 0
  Global XML$, Event.i
  
  
  EnableExplicit
  
  Runtime Enumeration ;Windows
    #WinMain
  EndEnumeration
  Runtime Enumeration ;Gadgets
    #CanvasTest
  EndEnumeration
  
    Runtime Enumeration ;Fonts
    #VFont_01
  EndEnumeration
  
  Runtime Procedure SetUP()
    Protected T$
    LoadFont(#VFont_01,"Arial",48)
    
    If StartVectorDrawing(CanvasVectorOutput(#CanvasTest))
      VectorFont(FontID(#VFont_01),20)
      T$ = ~"EscapeString\t\tTab test"
      VectorSourceColor($FF0000FF)
      MovePathCursor(10,10)
      DrawVectorText(T$)
      
      MovePathCursor(10,50)
      T$ + ~"\n" + T$
      DrawVectorParagraph(T$,200,72)
      StopVectorDrawing()
    Else
      MessageRequester("ERROR!","Cannot invoke Vector Drawing")
    EndIf
  EndProcedure
  
  XML$ = "<dialogs>"+
         "  <window id='#WinMain' name='CanvasTest' text='CanvasTest' minwidth='auto' minheight='auto' flags='#PB_Window_ScreenCentered |"+
         "  #PB_Window_SystemMenu | #PB_Window_SizeGadget'>" +
         "    <canvas id='#CanvasTest' height='250' width='250' />"+
         "  </window>"+
         "</dialogs>"
  
  If CatchXML(#Xml, @XML$, StringByteLength(XML$), 0, #XmlEncoding) And XMLStatus(#Xml) = #PB_XML_Success
    
    If CreateDialog(#Dialog) And OpenXMLDialog(#Dialog, #Xml, "CanvasTest")
      SetUp()
      Repeat
        Event = WaitWindowEvent()
      Until Event = #PB_Event_CloseWindow 
      
    Else  
      Debug "Dialog error: " + DialogError(#Dialog)
    EndIf
  Else
    Debug "XML error: " + XMLError(#Xml) + " (Line: " + XMLErrorLine(#Xml) + ")"
  EndIf

I'm not sure why it would work even on MacOS. PureBasic doesn't use escape sequences in strings.

Try:

Code:

String.s="Some"+#TAB$+"Thing"

Yes it does; it was added in the 5.40 release. Check this out:

Code:

string$=~"abc\t123"
Debug string$ ; Shows "abc   123"

Seems to be a limitation on GDI+, it doesn't handle tab unless you specify some tabstop array: https://docs.microsoft.com/en-us/dotnet ... drawn-text . It's no help for us here, as we don't know where to position the stop. Moved to doc for proper documentation

Added some words concerning Windows.
