* Added `nullchar` constant as the null terminator for strings and `NULLCHAR` feature to define its value.

* Added `vectrex`, `msx_br`, `koi7n2`, `iso15`, `zx80` and `zx81` text encodings.

|

|
||||
You can also append `z` to the name of the encoding to make the string zero-terminated.
|
||||
This means that the string will have one extra byte appended, equal to `nullchar`.
|
||||
The exact value of `nullchar` is encoding-dependent: in the `vectrex` encoding it's $80,
|
||||
in other encodings it's 0 (this might be a subject to change in future versions).

The exact value of `nullchar` is encoding-dependent:
