jupyter notebook with R cannot display specific Kanji (multibyte characters)
1
I am using jupyter notebook, but R kernel(IRkernel) sometimes die when inputting Kanji(japanese multibyte chars).
I've tried a few Kanji, and found that IRkernel dies when using specific Kanji characters. For example, '十', '能', '表', etc.

And this code works on native R environment fine, so I think this is IRkernel problem.
Thanks.

I am using jupyter notebook, but R kernel(IRkernel) sometimes die when inputting Kanji(japanese multibyte chars).
I've tried a few Kanji, and found that IRkernel dies when using specific Kanji characters. For example, '十', '能', '表', etc.
enter image description here
Above image is R concole. Below is Python console.
It doesen't work with R kernel only.
