+Subject: Avoid buffer overflow read in HFSReadNextNonIgnorableCodePoint
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Unicode codepoints goes beyond 0xFFFF.
+
+It exists upper and lower case characters there: `𞤡 `vs `𞥃`.
+
+The buffer overflow occurred when using the lookup table:
+```
+lower_case_table[codepoint >> 8]
+```
