This is a bug report.
After updating to 10.12.4 from 10.12.3,
character corruption of some of the received mails
occurred in Mail.app (ver. 10.3 (3273)).
The mails with character corruption were surely
readable before the update.

Try rebuilding the mailbox.
If that doesn't work, try re-indexing the mailboxes. This can take awhile if you have a lot of mail.
Reindex messages For El Capitan, try looking in V3. Sierra use V4
Reindex messages (2) See post by Linc Davis

Then I think it is some kind of encoding bug in Mail or in the Mail/gmail interaction. Let Apple know via

Could be applied and see if it works , or the best method I prefer is :
Take back of all mails in V4folder : Method for how to copy in V4 folder .
Click on go on top menu bar , hold option key click on > library > select mail folder > right click on mail there itself > click on copy mail > right click on extreme right hand side in column B , that is below persistence info.plist > click on paste item .
Entire mails are copied to V4 folder .
Go to the corrupted IMAP account , select it & click on minus sign it is deleted .
Configure new IMAP account , go to top menu bar ,file > import mail boxes > import data from > select apple mail > click on continue > select the back drop folder then choose new .
When new IMAP account is opened , a new folder with all mails will appear in the mail side bar .You can rename the folder .
Did you try to click on get mail icon the very basic step .

And post the results , it will help what could be reason of mail corruption , may be its due to some malware , anti - virus , cleaners , unwanted apps installed in the system .

Yes, the mails are written in Japanese.
I'm using IMAP gmail. And the old emails (previously received locally) and new comping emails are crashed.
Not all the emails but some of them.
I can still read the same (crashed) mail correctly in my iPhone or web browser (Safari).
report on progress:
I marked solved this problem, however still the problem remains...
After changing back the OS language to English, the problem appears again in macOS Sierra 10.12.5.
Now the problem is reported to Apple engineer and waiting for a response.
Thanks for the information.
However, the problem is macOS and Mail.app and rebuilding spotlight index doesn't help.
If the macOS language is English and receiving mail is Japanese, some of emails cannot be viewed correctly (character corruption occur).
The new receiving emails is also corrupted.
I hope this issue is solved in near future...
Thanks for your reply.
I attach a screen shot of an example email.
What I did before the occurrence is only the upgrading macOS, though.
Some of the received emails have character corruption.
Restoring standard fonts didn't solve the problem.
For font validation, I'm not sure which font to check...
I attach new screen shot that the preview shows correct body of email but main pane crushed.
I posted a new thread.
I hope this helps.
