Java halfwidth and fullwidth Conversion

1. Full-width unicode encoding from 65281 ~ 65374 (hexadecimal 0xff01 ~ 0xff5e );
2. The Unicode encoding of halfwidth characters ranges from 33 ~ 126 (hexadecimal 0x21 ~ 0x7e );
3. Spaces are special. The width is 12288 (0x3000) and the width is 32 (0x20 );
4. Besides spaces, the full/half-width values are sorted in Unicode encoding order;
5. Therefore, you can use the +-method to process non-space data and separate spaces.
