I have to work with a PDF form created by a person unknown to me. Why did the program with which the form was created (Word + PDF export?) **split the term "Stunde" into "S", "t" and "unde"** in line 6909 of the decoded PDF? There is no visual break between the three parts.

[![The resulting document part of the source code.](https://i.stack.imgur.com/3YrcZ.png)]

To get the source code above, I decoded the PDF file as described [here](https://stackoverflow.com/a/53141656/7427029). I have no know-how concerning the PDF file format.

**Background:** I had to replace the word "Stunde", it drove me crazy to find the place where "Stunde" was written (in parts) within the source code, since no free PDF editor seems to be able to work with horizontal text without problems.

**Academic Bonus questions:** Is it possible to set the sum over a column as default value for a form field? (Modifiable; changed every time the column is changed.) Why was I able to replace "Stunde" with "Einsatz" without making the PDF file corrupt due to now irregular offsets?
