Is $orig actually UTF-8 encoded at that time? If it only contains
codepoints <= U+00FF, it might be 1 byte/character, but when sent to
Oracle the codepoints between U+0080 and U+00FF will still be encoded as
two bytes.
Something like:
my $bs = encode_utf8($orig);
my $sbs = substr($bs, 0, $len);
my $truncated = decode_utf8($sbs, FB_QUIET);
would be safer.
Also, waht encoding do you use in Oracle? UTF8 isn't really UTF-8: It's
a weird double-encoding which may take up to 6 six bytes for non-BMP
characters. To get real UTF-8, use AL32UTF8.
