The characters on the signboard are replaced

When you enter text on a signboard, in rare cases, part of the text cannot be displayed and is replaced with #.
example
If you enter "Kanita Line"
"Kanit#####ne" is displayed
The example used is the alphabet, but it also occurs in Japanese.
This happens even though it doesn't contain violence, discrimination, nudity, or other sensitive words.
I have confirmed this since at least ver.1.20 was released.
