SYLK does not have support for Unicode. Even if a SYLK file is created by an application that supports Unicode (for example Microsoft Excel), the SYLK file will be encoded in the current system's ANSI code page, not in Unicode. If the application contained characters that were displayable in Unicode but have no code point in the current system ...
Unicode input is method to add a specific Unicode character to a computer file; it is a common way to input characters not directly supported by a physical keyboard. Characters can be entered either by selecting them from a display, by typing a certain sequence of keys on a physical keyboard, or by drawing the symbol by hand on touch-sensitive ...

However, with Unicode, mathematicians are free to use characters from any known script in the World to stand in for a mathematical set or mathematical constant. To date, Unicode has only added specific semantic support for a few such mathematical constants (for example the Planck constant, U+210E, and Euler constant, U+2107, both of which ...
