native_to_mb: my_charset_conv_wc_mb

Write a character to the target string, using its native code. For Unicode character sets (utf8, ucs2, utf16, utf16le, utf32, filename) native codes are equivalent to Unicode code points. For 8bit character sets the native code is just the byte value. For Asian characters sets:

• MB1 native code is just the byte value (e.g. on the ASCII range)
• MB2 native code is ((b0 << 8) + b1).
• MB3 native code is ((b0 <<16) + (b1 << 8) + b2) Note, CHARSET_INFO::min_sort_char and CHARSET_INFO::max_sort_char are defined in native notation and should be written using my_ci_native_to_mb() rather than my_ci_wc_mb().
