• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: 2.7.0
• Backport: 2.5: REQUIRED, 2.6: DONE, 2.7: DONE

[dmikurube (Dai MIKURUBE)]

Confirmed on: Ruby 2.6.3 and 2.7.0 on Mac OS X 10.13.

Time .now .strftime("%28c")

Expected:

"    Tue Apr  7 12:44:16 2020"

Actual:

"    \u0000ue Apr  7 12:44:16 2020"

Appendix:

• For "%c", 26 worked, but 27+ did not work.
• Confirmed similar for other recurred formats like "%R", "%F", and else.
