Issue: ERANGE errors when processing data with 4 byte characters .
# perl -e 'print "\xf0\x9f\x98\x80\n"' | wc
wc: : Result too large
The 32-bit locales and applications can only process the Basic Multilingual Plane (BMP), from U+0000 to U+FFFF.
The newer 4 byte characters, such as U+1F600 f0 9f 98 80 "GRINNING FACE", are in the Supplementary Multilingual Plane (SMP) from U+10000 to U+1FFFF.
Users might need to use the "wc" to validate data from their 64bit applications.
Do not place IBM confidential, company confidential, or personal information into any field.
