PDF output supports a limited character set. Some Unicode characters can cause the PDF rendering to fail. All Latin characters and other common characters like mathematical operators and Greek letters are supported. However, other special characters and characters from Asian languages may not be supported, depending on the operating system and installed operating system languages. If a character is not supported, it will be replaced with a question mark (?).
As of reporter v1.1.3, the package will generate PDF files directly, without using rmarkdown as an intermediary. This technique eliminates dependencies, makes the package easier to install, and greatly improves performance. It is recommended to use the most recent version of the package if possible.
For versions of reporter prior to v1.1.3, the package has additional dependencies and installation requirements. See details below.
For reporter v1.1.2 and below,
PDF output type requires the rmarkdown package and a
LaTeX renderer like MiKTeX.
MiKTeX must be installed separately, and will
not be installed as part of the reporter install. This program must
furthermore be added to the path environment variable on the system
where reporter will run, so that reporter can find it.
