Display bug in textdelay

[nomucoke]

Describe the bug

Strange symbols are displayed when using textdelay for certain characters (Japanese in this case)

Also, the same display will occur even if textdelay is omitted.
I think it should be displayed without delay if omitted (Same as when textdelay=0).

To Reproduce

1. View storyboards that use specific characters using fonts (Font used is meiryo).
2. Strange symbols are displayed when textdelay is executed.

Expected behavior

The text should be delayed correctly and whitespace should be displayed.
