Render problem of Arabic string with "(" symbol

[diydevdesign]

I'm working on convert SVG to PNG using svg-net in c#. the problem is when I meet Arabic character "(" or ")" . - (other characters no problem).

The position and direction of the "(" symbol is rendered differently than in the original SVG text .

text in SVG file render result

sample svg code is:

<?xml-stylesheet type="text/css"?>

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" contentScriptType="text/ecmascript" zoomAndPan="magnify" baseProfile="basic" contentStyleType="text/css" id="test" version="1.1" width="1080px" preserveAspectRatio="xMidYMid meet" viewBox="-15 -20 1095 1010" height="1440px" x="0px" y="0px">

</svg>

My development environment is as follows.

• VS 2017 , c# .net (4.6.1)
• svg-net (3.4.4)

My expecting result is below, expecting result

Additonally, I don't know how to change contents in svgDocument.

var svgDoc = SvgDocument.Open<SvgDocument>(tempSvgname);
svgDoc.GetElementById("A11").Children[k].Content = "changed text";

using (MagickImage img = new MagickImage(svgDoc.Draw(width * 2, height * 2)))
{
  // no change text in render result
  ...
}

Thanks for help. Note1. This problem does not occur when viewing svg files in chrome. Note2. I have attached the svg file that causes the problem.

Finally , I've solved my problem, so I'll write down my solution.

In svg-net, this problem could not be solved, and the problem was solved by directly modifying the text string in the svg file.

If the string is in Arabic, adding "&#8207 ;" symbol to the end of the string, hass rendered it correctly.

bool isArabic = false;
string[] svgTexts = File.ReadAllLines(filename);
for (int k = 0; k < svgTexts.Length; k++)
{
    string cline = svgTexts[k];
    if (cline.IndexOf("<text") != -1)
    {
        int tmpPos = cline.IndexOf(">");
        string curText_prev = cline.Substring(0, tmpPos + 1);
        string curText = cline.Substring(tmpPos + 1, cline.IndexOf("</") - tmpPos - 1);

        if (IsRtl(curText)) // case of string is Arabic
        {
            curText += "&#8207;"; // add "&#8207;" 
            isArabic = true;
            svgTexts[k] = curText_prev + curText + "</text>";
        }
    }
}
if (isArabic)
{
    File.WriteAllLines(filename, svgTexts);
}


// check Arabic text
private static bool IsRtl(string input)
{
    return Regex.IsMatch(input, @"\p{IsArabic}");
}
