Replace Text does not seem to work

[craftyweb]

Hi,

Currently we are looking for a good solution to edit pdf template to send to customers.

We are building a test case with gift cards. A customer can choose the amount of the gift card and we would like to display the requested amount and also the generated code to use the gift card online.

We are trying now with the trial api key but we are facing some issues.

We have a pdf template with some text on it and some text we would like to replace with dynamic content.
for example: we replace #AMOUNT# with the requested amount (in our case we would like to see "Bedrag: €25,00")

In the image below you can see two issues

1. there are some squares around the letters. How can we remove this?
2. Only known letters seem to be replaced. Other examples I find online doesn't seem to have the same problem. What do we do wrong?

Overall great library that we would like to use if our problems are fixed

is this a possibility with IronPDF? I'm struggling to find any documentation on this topic
