Invisible red dot UNICODE character

Recommended Posts

'F‌inal' ; <========= problem between F and i

'Final' ; <========= Notepad ANSI, no problem

F‌inal :)

PostgreSQL complains about that red dot.  Notepad++ marks the first word.

Notepad said it contains Unicode.  Saved as ANSI and put back. Red dot is gone.

 

the Text is inserted manually into an AutoIt Input box.  Things get done to it, and it ends up in a SQL database.  The data seems fine, but when I start generating reports, all kinds of funny problems show up.

 

If I can ID that character, I can remove it.

Any ideas?

With a bit broader range of removal:

StringRegExpReplace('F‌inal', '[\x{200B}-\x{200D}]', '')

Yet removing ZWJ (U+0200D) may change semantic of Unicode flux in some languages.

You may also discover other such special codepoints, depending on the nature of the input text.

Going by the character which my browser claims to be in between F and i, it is a Zero-width non-joiner character in unicode (code point 8204), it is used in some languages to represent more complex writing systems :)

      Hi all,
      I'm reading the file https://msedgedriver.azureedge.net/LATEST_RELEASE_83 using WinHTTP, and the string I get back looks like this when I view this file in Scite --
      xEFxBFxBF83.0.478.54 Here's what I've come up with as a means to strip off the Unicode BOM from the beginning of the string --
      If Asc($sDriverLatest) = 255 Then ConsoleWrite("Unicode detected!" & @CRLF) $sDriverLatest = BinaryToString($sDriverLatest, $SB_UTF16LE) If Asc($sDriverLatest) = 63 Then $sDriverLatest = StringMid($sDriverLatest,2) ; skip ? EndIf ConsoleWrite("Latest=" & $sDriverLatest & @CRLF) Is there a more reliable way to eliminate these unicode characters?

      Good morning,
       
      I am trying to read a Unicode utf8 string from a perl subprocess via StdoutRead.
      I use an AUtoIt GUI and display result in an 'Edit' control (see my code below) using 'Courier New', a font that can handle Unicode characters.
      I was expecting a result looking like (CMD console):
      ++$ chcp 65001>NUL: & perl -Mutf8 -CS -e "use 5.018; binmode STDOUT,q(:utf8); say qq(\x{03A9})" & chcp 850>NUL: Ω Instead I get someting like this (see downward the screen copy):
      ++$ chcp 1250>NUL: & perl -Mutf8 -CS -e "use 5.018; binmode STDOUT,q(:utf8); say qq(\x{03A9})" & chcp 850>NUL: Ω Obviously while I was expecting to receive an utf8 char, it seems to have been converted to Windows ANSI codepage 1250 (Windows default for Western/Central Europe, right ?)
      What am I doing wrong? Is there someone who could guide me?
       
      Here is my code and my output in the GUI.
      Creating and configuring the Edit control:
      Local $Edit1 = GUICtrlCreateEdit( "", 20, 110, 780, 500, BitOr($GUI_SS_DEFAULT_EDIT,$ES_MULTILINE,$ES_READONLY) ) GUICtrlSetData($Edit1, "This field will contain text result from external Perl command") GUICtrlSetFont($Edit1, 10, $FW_THIN, $GUI_FONTNORMAL, "Courier New")  
      Executing Perl command (note: `-Mutf8` and `-CS` garantees that I work in utf8 and STDOUT accepts wide-characters):
      local $ExePath = 'perl.exe -Mutf8 -CS ' ;~ if perl in PATH, no need for full path C:\Perl\bin\perl.exe local $Params = '-e "use 5.018; use utf8; use charnames q(:full); binmode STDOUT,q(:utf8);' & _ 'say scalar localtime; say qq(\N{GREEK CAPITAL LETTER OMEGA})"' local $Cmd = $ExePath & ' ' & $Params Local $iPID = Run($Cmd, "", @SW_HIDE, BitOR($STDERR_CHILD, $STDOUT_CHILD))  
      Reading STDOUT and displaying it into the Edit control:
      While 1 $sOutput &= StdoutRead($iPID) If @error Then ; Exit the loop if the process closes or StdoutRead returns an error. ExitLoop EndIf WEnd If $sOutput <> '' Then GUICtrlSetData($Edit1, $sOutput) EndIf  
      And now, what I get on my GUI:

      Hi dear
      With this script you can print Unicode text in the CMD screen
      the script is  easy to use
      just you  write the text that contains Unicode in the first input
      and the script automatically reflect the code in the second input
       you can copy the text to the clipboard
      or you can try printing the text in the CMD window
      I apologize to everyone for colors and shape if not appropriate
      I'm a blind man and I do not see
      Thank you for your understanding
      Greetings to all of youCmdUtM.au3

      Hello
      I'm using the code below to send mails using our internal relay server. 
      We got a Helpdesk system named Remedy. Our users can send us a mails using outlook 2010, and we'll get a ticket.
      The problem is if I send a mail using the above script our ticket system can't display unicode characters, like ex: Æ Ø Å. It will display them as: questionmarks: "? ? ?" inside our ticket system. In the outlook inbox it looks fine showing unicode symbols, but in our ticket system the unicode characters will be replaced by questionmarks.
      The thing is, if they send a mail using outlook, it works fine, but using the script above it doesen't.
      I tried to save my script with encoding: UTF-8 with BOM, but it didn't fix it.
       
      All suggestions are very welcome
