## file-character-position

Arguments: simple-stream

This generic function tries to determine the character position of its `simple-stream` argument, similar to stream-line-column which tries to determine the character number from the beginning of a line. The value returned is a non-negative integer or `nil`.

`nil` means that the value cannot be determined. This can happen, for example, if bytes rather than characters have been read from simple-stream or the file-position has been set. Unlike stream-line-column, which can re-synchronize itself after reading a newline, file-character-position cannot; it can only re-synchronize itself when the file-position starts at zero and only characters are read.
