different results between chunk and knitted markdown / Cyrillic letters

[zoowalk]

I encountered a surprising behavior when knitting an .Rmd document.
Below the code.

When running only the chunk, the result of str_count is 1.
When I knit the document, the result is 0.

When I change the search pattern to a term without cyrillic letters, e.g. "decision" there is no difference.

Any idea what's going on? Is this a bug, or am I missing something? Many thanks.

Since the subject-matter of the case was limited to the former provision, section 33(1)(c) was not reviewed for constitutionality."

str_count(txt, regex("обн\\."))

Hi, many thanks for your reply.

The result remains the same, meaning they differ. When I run the chunk it's 1, when I knit it's 0. I strongly assume it has something to do with the Cyrillic letters. When I change the search pattern to a term written in the Latin alphabet it's fine.

I ran the code on my RStudio Cloud account and there the results are fine. It's the same R Version ("R version 4.0.3), the same knitr (1.37), stringr (1.4.0) and Rmarkdown (2.11) version.

Below the output. Any idea?

Just to add - I update to R vers 4.1.2 and the riddle remains.

Try File | Reopen with Encoding | UTF8.

Sort of a long shot, though.

[zoowalk]

Thanks again. Unfortunately, the problem remains. Maybe it's best to file an issue at the knitr (?) repository.

[zoowalk]

got this as an answer. so you were on to something with UTF8. thx again.
