In expand.h:
/** Character for separating two array elements. We use 30, i.e. the ascii record separator since that seems logical. */
#define ARRAY_SEP 0x1e
/** String containing the character for separating two array elements */
#define ARRAY_SEP_STR L"\x1e"
This results in:
xiaq@blackie ~> set a (printf 'a\x1eb')
xiaq@blackie ~> count $a
2
xiaq@blackie ~> set a (printf 'a\x1fb')
xiaq@blackie ~> count $a
1
It's clear that the char \x1e is treated specially as element delimiter.
