No such function is part of the SQLite core. But I wrote an extension
offering
As Simon said use substr() to get first character and use cast(X'FF'
as text) to convert some hexadecimal character code to symbol (in my
example the code is FF = 255). But there's no way to convert character
into its code, so you cannot do any arithmetics with it though you
probably don't need it
