The OpenDocument specification, which specifies formulas that should be supported by spreadsheet applications, defines a number of so-called byte-position text functions. These functions are currently not supported in kspread, and adding support for them is rather easy as they can just be aliases for the character-position text functions (these functions are FINDB, LEFTB, LENB, MIDB, REPLACEB, RIGHTB and SEARCHB). Expected outcome is a patch to the kspread sourcecode that adds support for the byte-position text functions, by adding them as alias to the character-position text functions.
