Why numbers getting reversed when formatted in RTL Arabic - Rails application?

Question

I'm using Prawn gem in my Rails app to generate PDF reports.

I read the documentation for putting the text in Arabic with text_direction RTL in arabic.

But, issue is that numbers are getting reversed here.

I wanted semester 1234 as الفصل الدراسي 1234,

but in my app the output is الفصل الدراسي 4321.

My two lines of code is here:

pdftable = Prawn::Document.new
pdftable.text(t('org.semester') + " " + @semester)

@semester = '1234' (The reason would be that it is being treated as a text/string, thus changes to RTL (reversed))

Anyway, Please help me to retain numbers in proper order without changing the RTL format.

Answer 1

Without hacking too much you could use

@semester.to_s.reverse

So you reverse the string twice
