 <icu:charsetFamily>           "ASCII"
 
 # 'p' is for the range that may produce non-BMP code points.
+# 'i' is to make the code range illegal.
+# Big5 has a lot of small holes in the 2nd byte. If it's in the ASCII range,
+# the 2nd byte has to be added back to the stream to be compliant to the
+# encoding spec. Each state adds 1kB in the data size.
