+ISO-2022-CN-EXT: fix out-of-bound writes when writing escape sequence
+
+The iconv() function in the GNU C Library versions 2.39 and older may 
+overflow the output buffer passed to it by up to 4 bytes when converting 
+strings to the ISO-2022-CN-EXT character set, which may be used to 
+crash an application or overwrite a neighbouring variable.
+
+ISO-2022-CN-EXT uses escape sequences to indicate character set changes
+(as specified by RFC 1922).  While the SOdesignation has the expected
+bounds checks, neither SS2designation nor SS3designation have its;
+allowing a write overflow of 1, 2, or 3 bytes with fixed values:
+'$+I', '$+J', '$+K', '$+L', '$+M', or '$*H'.
