Format description text (REST API)

miss something, how do you send the character 0xD and 0xA accross an HTTP resquest (\n\r)?
I can send only printable charact

    public String createIssue(String project, String summary, String description) throws IOException
    {
        final URI uri;
        try {
            uri = new URIBuilder(serviceLocation + "/rest/issue").addParameter("project", project)
 .addParameter("summary", summary)
 .addParameter("description", description)
 .build();
        } catch (URISyntaxException e) {
            throw new RuntimeException(e);
        }
        final HttpResponse response = httpClient.execute(new HttpPut(uri));
        final StatusLine statusLine = response.getStatusLine();
        final HttpEntity entity = response.getEntity();
        final String responseText = entity == null ? null : EntityUtils.toString(entity);
        throwExceptionsIfNeeded(statusLine, responseText);

        final Header header = response.getFirstHeader(HttpHeaders.LOCATION);
        if (header == null) {
            throw new YoutrackAPIException("Missing location header despite positive status code: " + statusLine.getStatusCode());
        }
        final String issueURL = header.getValue();
        final Matcher matcher = Pattern.compile(".*(" + project + "-\\d+)").matcher(issueURL);
        if (!matcher.find() || matcher.groupCount() < 1) {
            throw new YoutrackAPIException("Cannot extract issue id from issue URL: " + issueURL);
        }
        return matcher.group(1);
    }

    public String createIssue(String project, String summary, String description) throws IOException
    {
        final URI uri;
        try {
            uri = new URIBuilder(serviceLocation + "/rest/issue").build();
        } catch (URISyntaxException e) {
            throw new RuntimeException(e);
        }
        final HttpPost request = createPostRequest(uri, new BasicNameValuePair("project", project), new BasicNameValuePair("summary", summary),
            new BasicNameValuePair("description", description));
        final HttpResponse response = httpClient.execute(request);
        final StatusLine statusLine = response.getStatusLine();

I am sorry to resurrect this old issue, but I was not able to find the information I seek otherwise (and link to this issue came up quite high in my Google search).

I am looking for a way of formatting the issue description using the current Markdown support in YouTrack. AFAIK there are two flavours of markdown, one that was used at the time of writing the original post here, the other that is used now (and that is consistent with Common Mark). However, using REST API, I can still only use the old markup format. Is there a way to change this behaviour?

Hi!

I'm Sergey from the YouTrack team.

there are two flavours of markdown

There are Markdown and Wiki. This thread is about Wiki syntax. We deprecated Wiki syntax a couple of years ago. Yet, we continued to render Wiki for old content for a while, and it was available in the REST API. In the recent 2022.2 update, all the Wiki parts were removed from the codebase completely.

So please upgrade to the last build of 2022.2 version, and you will only have the Markdown option by default.

Many thanks Sergey for your quick answer.
