coff = CharOffset(s$, boff[, encoding])
boff
, in bytes and starting from 0, inside string s$
.
The optional 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 #ENCODING_ISO8859_1
.
To convert a character offset into a byte offset use the ByteOffset() function. See ByteOffset for details.
coff = CharOffset("äöü", 2) Print(coff)If Hollywood is in Unicode mode, this will return 1 because the "ä" character takes up 2 bytes in UTF-8 code space. In ISO 8859-1 there is no difference between characters and bytes, so 1 will be returned in that case.
