[vietj]

can you give more details like a reproducer or a stack trace otherwise we will need to close this issue

[jr981008]

Sorry. It seems that GitHub has a file size limit for image uploads, and I must have missed the upload failure. Below is the stack trace content. I see there have been some modifications made to the isDIGIT method in the recent version.
