Default charset is "UTF-8". If you need different, consider to use one of:
- US-ASCII Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set
- ISO-8859-1 ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1
- UTF-8 Eight-bit UCS Transformation Format
- UTF-16BE Sixteen-bit UCS Transformation Format, big-endian byte order
- UTF-16LE Sixteen-bit UCS Transformation Format, little-endian byte order
- UTF-16 Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark
