            Bug ID: 27675
           Summary: U+FFFD in euc_kr index
           Product: WHATWG
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Encoding
          Assignee: annevk@annevk.nl
          Reporter: public+w3@mearie.org

The updated euc_kr table now has the following entries:

---8<---
 5916    0xFFFD    � (REPLACEMENT CHARACTER)
 5917    0xFFFD    � (REPLACEMENT CHARACTER)
 5918    0xFFFD    � (REPLACEMENT CHARACTER)
 5919    0xFFFD    � (REPLACEMENT CHARACTER)
 5920    0xFFFD    � (REPLACEMENT CHARACTER)
 5921    0xFFFD    � (REPLACEMENT CHARACTER)
[snip]
 5948    0xFFFD    � (REPLACEMENT CHARACTER)
 5949    0xFFFD    � (REPLACEMENT CHARACTER)
 5950    0xFFFD    � (REPLACEMENT CHARACTER)
 5951    0xFFFD    � (REPLACEMENT CHARACTER)
 5952    0xFFFD    � (REPLACEMENT CHARACTER)
 5953    0xFFFD    � (REPLACEMENT CHARACTER)
---8<---

They correspond to byte sequences A0 5B..60 and A0 7B..80, which are gaps
between UHC ranges. I don't think Bug 16691 intended this (as they are the only
occurrences of U+FFFD throughout the indices at the moment). This causes an
otherwise valid decoder to accept those sequences even when the fatal mode is
in the use.
