Thank you Steve.
First of all, I have tested your idea and I have sent the PDF version to another countries. Now, I am waiting for news!
As you suggested, I set all objects to 'Viewer's system locale'.
Now, the correct flow will be the next:
0- I send a blank PDF form to United States.
1- In United States a determined employee will fill up all currency fields that will be showed with dollar symbol.
2- That person sends that PDF form to me via e-mail.
3- Despite of my locale configuration, I will be the values with dollar symbol (if I read the values with another symbol, the information will be incorrect).
I only see a problem...,
- I have to send a PDF to Beijing and I have to read the result with 'euros' symbol. I have placed in the root a variable in 'initialize' method that checks the locale configuration in the user. If the city is Beijing, the currency has to be 'euro' (only there is this exception).
Thanks in advance.
I'll let you know the result.
Best regards,
Roberto
