Arabic Text Replace in PDF Using Aspose.PDF REST API Adds Weird Space and Font


I am applying aspose on arabic text. I have created a pdf file and it has a custom arabic font. When I do the replace, the font becomes different and there is a weird large space inserted as displayed in images.

Fonts displayed on output pdf:

The output

Code Below:
$textReplace = new TextReplace([
“old_value” => “[ARNAME]”,
“new_value” => “محمد”,
“regex” => false

    $textReplaceRequest = new TextReplaceListRequest([
        "text_replaces" => [$textReplace],

    $textReplaceRequest->text_replaces = [$textReplace];
    $response = $pdfApi->postDocumentTextReplace(
        null,   // Storage
        null    // Folder

Any help?

kindly note that the first sentence will not work and that’s ok. The focus is on the second one.


Please note for Arabic text replace in PDF you need to use Font and FontFile property of TextState for custom fonts as follows. Kindly update your custom font to the cloud storage and pass its name and path in the Font and FontFile properties respectively. It will help you to accomplish the task.

Thank you I did that and now it takes the font but messes up the first word as show in the picture



It also does not solve the space/gap issue.

Can I have some more help please? I am very grateful!
