--- Comment #10 from Julien Nabet <serval2412 at yahoo.fr> ---
ANSI seems to correspond to Windows-1252 (see
https://en.wikipedia.org/wiki/ANSI_character_set).
quotation from Wikipedia:
"
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's code page, they will be converted to
question marks ('?') in the SYLK file.
"

Wikipedia also indicates 260 for max number of characters
(https://en.wikipedia.org/wiki/SYmbolic_LinK_(SYLK)) but does it include the
format record too or just the cell value? Also what about columns which must be
doubled? Do we count the initial string or the string modified?

But the biggest problem is:
"Microsoft does not publish a SYLK specification"
Should we really support it?
Is this still really used?
Perhaps should we remove export part and keep import part?
