convert mac address string to byte array java

Using ISO8859 to obtain bytes will result in garbled characters, because ISO cannot represent UTF-8 characters, and will be replaced with a ? sign).īecause the code generation is different, it will include whether to specify the encoding format, and the encoding itself may be Utf8 or GBK, and the binary information will be lost in the process of String conversion.

(If the UTF-8 encoding is specified, the returned result is already utf8. In some cases, you can use his single-byte character characteristics to convert bytes and characters.īut because of the existence of rule 2 above, using this code set to make bytes is somewhat problematic. It is not an encoding set that can represent Chinese. This encoding set is a simple encoding set with one character per byte. Note that there are many references to the 'ISO-8859-1' encoding set on the Internet.

Not mandatory, and there are two main encoding formats in Chinese, GBKand UTF-8。 If an encoding set is specified, use the character set specified by the encoding. If no encoding set is specified in the code, this encoding format is used by default.Ģ. This encoding format is used to interpret Byte data.ġ. Zxing can add default en coding format in Hints.

Zxing3.2.1I have encountered the problem of garbled code scanning on Android Zxing before, and I searched the Internet and solved it.
