Both csgero and bzlm pointed in the right direction. Cheers, Aldis :) Share. As I read through the answers I notice that there are several remarks and alternatives to the currently marked answer. The reason that all your characters had ordinal in the ASCII range is that UTF-16 extends ASCII in the sense that characters 0 to 127, in the ASCII range, have the same ordinal value in UTF-16. I suspect that because you ask us to write the code for you rather than help you understand. This page shows the extended ASCII table which is based on the Windows-1252 character set which is an 8 bit ASCII table with 256 characters and symbols.

A vertical tab (VT) also exists and has ASCII decimal character code 11 (control+K or ^K). In D2009+, you can use either: Char($221E) or Char(8734) (in earlier versions, use WideChar() instead) Chr($221E) or Chr(8734) #$221E or #8734 character constants. – In the . 5 (shipped with Delphi 2010) for: connecting to telnet server performing username/password authentication (gaining access to the command shell) executing a command with Need some sample code to study. Word or UInt16 is also appropriate, because now that the string type is Unicode, a character is represented by two Delphi strings are encoded internally as UTF-16. More likely would be that the text is either ASCII or encoded in the current code page. Notice that the ASCII format does not preserve wide characters. Then it would show something like 'w' is 119. Graphics unit contains definitions of useful constants for TColor. My guess is that if the library does not state a code page, then the text is encoded in the current code page.

If so, then use any ol' encryption scheme, but Base64 encode the string. Your Delphi's editor is perfectly capable of working with the codes directly, you can safely use them in your pascal source files. Wikipedia has pages for most Unicode symbols, and includes the Unicode codepoint for them. No conversion required. First solution could be to use Delphi 2009 and later. These key codes do not distinguish between left/right There's no advantage to using the ASCII value of D in the search -- it would just obfuscate the code. Toggle Excel subsection. In the Form. Chr returns the character with the ordinal value (ASCII value) of the byte-type expression, X. (ignore the 'why' of it; let's just blame it on a legacy code). Follow answered Nov 5, 2014 at 11:29. – This is one of my first projects with delphi and pascal when at Jun 7, 2006 - alikadir/delphi-basic-ascii-code-detector You are going to assign a Unicode character to an ANSI character in the above code.
