Noto Sans CJK TC, that is suggested as a character set that contains Japanese characters, may not be suitable to properly display Japanese characters. Rather, Noto Sans CJK JP is much more recommendable for that purpose.
Although some characters originated from China are quite similar among countries/regions, most of them have evolved into different shapes in Mainland China, Hong Kong, Taiwan, Japan, Korea, and Vietnam. Therefore, it is best to use a character set that the language of the country/region uses for the readability/recongnizability sake. See also [an webpage that discusses the glyph appearance issue in Chinese, Japanese, Korean, and Vietnamese languages](https://heistak.github.io/your-code-displays-japanese-wrong/).
[README of Noto CJK](https://github.com/googlefonts/noto-cjk/blob/main/README.md) may be also good resource to know which font should be used to display characters of each language.
- For LineEnding use lowercase constructors, e.g. `crlf`, `native`.
This was the original intent, but there was a bug in the
implementation.
- For HTMLSlideVariant use lowercase constructors.
- For ReaderOptions use e.g. `default-image-extension`
instead of `readerDefaultImageExtension` for field names.
- For Extension, use e.g. `tex_math_dollars` instead of
`Ext_tex_math_dollars` as constructor.
- For Extensions, use an array of Extensions, instead of
an object wrapping the tag `Extensions` and an integer.
(The representation is not supposed to be part of the
public API.)
- For Opt, use field names like `tab-stop` instead of `optTabStop`.

Also, use absolute links to pandoc.org when possible, so that
