Multilingual Title

I'm Japanese and my Windows 10 is setup for 1.Japanese and 2.English.
Questions:
1. When my score is uploaded with an English title, can other countries access the score?
2. When my score is uploaded with a Japanese title, how is the score handled on other countries' PC?
3. When my score is uploaded with both Japanese and English title, how is the score handled on other countries' PC?

I'm using both Japanese and English mixed for the "title", "score Info" and .mscz File Name etc, believing that people in Japan and outside countries can access my score. But I began to think I may be wrong, because other countries' PC are not set up to handle Japanese.
Do I need to upload two scores, one in Japanese and one in English to give accessibility to Japan and outside?
If needed, please check my Musescore account "DIYJii". I have 9 scores there, now. All titles are Japanese/English mixed.
