Sabre special characters

Question

I'm using Sabre web services (SabreCommandLLSRQ) to build a c# proof of concept for low fare re-booking.

I'm now hitting some special sabre characters that I don't know what they are in c#. I have a few that are working but I'm sure to encounter more - does anybody have a sabre character mapping for c#?

private string BuildPriceLine()
{
    const char CHLOR = (char)0xE7;   // Cross-of-Lorraine
    const char ENDITEM = (char)0xA7; // End Item key
    const char CHGKEY = (char)0xA5;  // Change Key

    var sabreCommand = new StringBuilder();

    // WPRQ‡AAA‡UN*C123456‡KP0‡XP«
    sabreCommand.Append("WPRQ");
    sabreCommand.Append(CHLOR);
    sabreCommand.Append("AAA");
    sabreCommand.Append(CHLOR);
    sabreCommand.Append("UN*C123456");
    sabreCommand.Append(CHLOR);
    sabreCommand.Append("KP0");
    sabreCommand.Append(CHLOR);
    sabreCommand.Append("XP");
    sabreCommand.Append(WhatSabreCharIsThis); // "«" ?

    return sabreCommand.ToString();
}

I ran across this character set a while back. I could not get any relevant items to play nice using them in c# and passing into the SabreCommandLLSRQ. — fuchs_tx, Aug 02 '15 at 23:23
I think '«' is just an end of line / return character - not something you'd pass as part of your SabreCommandLLSRQ — Pj., Aug 03 '15 at 06:24
Just to confirm these are the only 3 special characters I've encountered needed to be used when working with the Sabre API in the 8 years I've been working with their web service. The next challenge will be dealing with those special characters in an XML response from the sabre webservice to a .Net application. Watch out for the invisible characters. — Mr Harno, Jul 22 '16 at 08:37
As best practices by Sabre you should avoid to use SabreCommand in your API's, you should use a webservice to perform this transaction — Mr Milk, Jul 02 '19 at 16:24

When you want to insert special Sabre characters in your XML, this is what I've got documented for Sabre Web Services SabreCommandLLSRQ service:

<!--Use &#231; for Cross of Lorraine-->
<!--Use &#164; for Change-->
<!--Use &#167; for End Item-->

Cross of Lorraine is the most commonly used one, but End Item and Change are also used.

Pj is correct. When you hit 'Enter' in the terminal window to send that command as an agent would that character appears. Don't include it with your request.

SabreCommandLLSRQ response returns damaged by double encoding string (from Sabre + our Java WS framework side). For Java I have:

public static String decode(String termRsp) {
    try {
        String fromUtf8 = new String(termRsp.getBytes("ISO-8859-1"), "UTF-8");
        String fromLatin1 = new String(fromUtf8.getBytes("ISO-8859-1"), "windows-1252");
        return fromLatin1;
    } catch (UnsupportedEncodingException e) {
        return termRsp;
    }
}

It seems many Windows code page encodings are fine for final conversion. They have dagger ‡ / yen ¥ / currency ¤ / section § signs in the same code positions:

https://en.wikipedia.org/wiki/Windows-1252
https://en.wikipedia.org/wiki/ISO/IEC_8859-1 - doesn't define dagger ‡, so the we need cp1252.

Correspondence between Sabre encoding and cp1252 can be seen in https://sds.sabre.com/XTRANET_Access/sabre.htm (in ALT Entry).
