UTF-1

UTF -1 was the first UCS Transformation Format for Unicode and ISO 10646 was published in 1993 and G of the original version of ISO 10646 in the appendix, however, is no longer part of this standard. UTF- 1 is based on ISO 2022 and has never been enforced.

UTF -1 using 8-bit bytes. ASCII characters, C0 and C1 control characters are encoded unchanged as described in ISO 8859. Other characters are variable length coded ( MBCS ), where ASCII characters can be part of an encoding. For example, UTF -1 has various disadvantages, as is the slash part of encodings can not be used for file names, therefore.

Instead of UTF -1 UTF -8 has become generally established.
