RTL Support issue in PDF export

[wada3n]

Hi,
I would like to thank you for your hard work and dedication to developing Denaro. I am a big fan of the software and I appreciate all the effort that you put into making it a great product.

I am using the Denaro to track my finances. I am using the Arabic language and I am exporting PDF files. When I choose an Arabic currency symbol, such as "دج", the numbers are displayed upside down.

For example, the number 1000 is displayed as "0001". This is a problem because it makes it difficult to read and understand the PDF files.

I have attached a screenshot of the issue.

- Expected behavior:

The numbers should be displayed correctly, with the thousands digit to the left and the units digit to the right.

- Possible solutions:

One possible solution is to change the way that the Arabic currency symbols are handled when exporting PDF files.

Thank you for your time and consideration.

Hi. Can you copy and paste the troubleshooting information from the about>Troubleshooting page of Denaro? That'll make it easier for me to reproduce this. LC_NUMERIC and LC_MONETARY are probably the important variables there.

Oh so its just the currency symbol thats set to Arabic not the system locale?

[JoseBritto]

We've got two problems here.

1. The character دج causes the text its used in to flip.
2. That character isn't rendered properly in the pdf.

In the App gui it causes the currency symbol and the + and - sign to be on the other side but doesnt flip the number.

@wada3n Thanks for reporting this bug. I'll try to see if I can do something when I get home :)

Hi @JoseBritto ,
I can live with issue 2 inside the app, but it's quite annoying when exporting PDF files.

I really appreciate the way you implemented the currency symbol positioning option in the app. It's a very thoughtful solution that technically solves the problem. Arabic is written from right to left, so selecting the last option in the dropdown menu actually fixes the issue.
It is true that it turns the format opposite to the intended idea in the application, but it is acceptable, while the big problem is in exporting to PDF.
I'm excited to see what you come up with in the future.

Thanks again for your dedication and hard work. I'm a big fan of Denaro!

Issue 1 is a known bug in QuestPdf QuestPDF/QuestPDF#752
I'll see if I can implement the workaround

[JoseBritto]

Splitting the number and symbol into different text blocks seems to fix this but I couldn't figure out how to get the formatting right.

With the C++ rewrite coming, QuestPDF won't be used anyway...so I say let's see what happens in the rewrite

[wada3n]

Well, no problem at all, I can live with it by choosing another symbol "DZ"
Thank you both @JoseBritto & @nlogozzo for the great effort you are doing.
Waiting for c++ version 🎉
