len = ByteLen(s$)
s$in bytes. If you need to know the string length in characters, use StrLen() instead. See StrLen 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.
len = ByteLen("äöü") Print(len)If Hollywood is in Unicode mode, this will return 6 because each of the characters needs two bytes in the UTF-8 character encoding. In ISO 8859-1 mode, there is no difference between characters and bytes which means the code above will return 3.
