Japanese localisation output size increases considerably than the other languages output

Hi Yu Ying Lin,

Thanks for reaching out and I'm sorry to hear you've hit this snag!

I've seen that using MS Gothic font can make the file size smaller. If you're comfortable sharing your file, I'd be happy to do some further testing on my end! You can upload it here or share it privately in a support case. We'll delete it as soon as troubleshooting is complete.
