boff = ByteOffset(s$, coff[, encoding])
s$. This offset is in characters, starting from 0.
encoding parameter can be used to set the character encoding
to use. This defaults to the default string encoding set using SetDefaultEncoding().
See Character encodings for details.
In the UTF-8 character encoding a single character may need a storage space of up to
4 bytes. In the ISO 8859-1 character encoding there is no difference between byte and
character sizes. Hence, it doesn't really make sense to call this function with the
character encoding set to
To convert a byte offset into a character offset use the CharOffset() function. See CharOffset for details.
boff = ByteOffset("äöü", 2) Print(boff)If Hollywood is in Unicode mode, this will return 4 because the two characters before the "ü" take up 2 bytes each in UTF-8 code space. In ISO 8859-1 there is no difference between characters and bytes, so 2 will be returned in that case.
