w = CharWidth(s$[, pos, encoding])
s$. The position must be specified in characters, not in bytes. The
posargument is optional and defaults to 0, i.e. the beginning of the string, if omitted.
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
w = CharWidth("ä") Print(w)If Hollywood is in Unicode mode, this will return 2 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.
