Encode::from_to($string, SOURCE, TARGET) changes all characters which
are missing in TARGET into '?' chars (ok, to be exact <subchar>s). This
is probably the most reasonable *default* behavior. But I could give
a couple of arguments why other behavior (not to change those chars
missing in target encoding) is also reasonable and sometimes much more
reasonable.
My native language, Russian, suffers from having FIVE one-byte encodings
(windows-1251, koi8-r, iso-8859-5, cp866, "MacCyrillic") which are used
everywhere alternately more or less often. Conversions from 1
encoding to another are very often, and sometimes we just have to make
the reverse conversion.
MY QUESTION IS: how can I convert text from 1 one-byte encoding to
another without changing into '?' (leaving unchanged) characters missing
in target encoding?
I did try to find it out myself. At some point I thought that
from_to($string, SRCenc, TGTenc, ENCODE_LEAVE_SRC)
is just what I wanted, because it LEAVEs those chars in SRC that
ENCODE_NOREP... but unfortunately no, it leaves all source string
untouched unconditionally.
Thanks in advance for any clues.
If my English and/or my question is far from clear, please tell me and
I'll do my best to rewrite it in other words.
