This error comes from the following fragment in lread.c:read1
case '?':
{
int modifiers;
int next_char;
int ok;
c = READCHAR;
if (c < 0)
end_of_file_error ();
/* Accept `single space' syntax like (list ? x) where the
whitespace character is SPC or TAB.
Other literal whitespace like NL, CR, and FF are not accepted,
as there are well-established escape sequences for these. */
if (c == ' ' || c == '\t')
return make_number (c);
if (c == '\\')
c = read_escape (readcharfun, 0);
modifiers = c & CHAR_MODIFIER_MASK;
c &= ~CHAR_MODIFIER_MASK;
if (CHAR_BYTE8_P (c))
c = CHAR_TO_BYTE8 (c);
c |= modifiers;
next_char = READCHAR;
ok = (next_char <= 040
|| (next_char < 0200
&& strchr ("\"';()[]#?`,.", next_char) != NULL));
UNREAD (next_char);
if (ok)
return make_number (c);
invalid_syntax ("?"); <<<<<<<<<<<<<<<<<<
}
Can you step through this in a debugger and see what character is seen
in next_char at the end of this snippet, and what value is in `c' at
that point, when it fails? The function read_escape called by this
fragment could also be of interest.
