Regression tests, UNICODE vs ASCII

At least 2 code pages contain a couple of BiDi control characters:
* Left-to-Right Mark (LRM) and Right-to-Left Mark (RLM) present in
both 1255 and 1256 code pages (0xFD and 0xFE);
* Zero Width Non-Joiner (ZWNJ) and Zero Width Joiner (ZWJ) -- in
cp1256 (0x9D and 0x9E).

One thing you may try are the explicit BiDi specifiers (Right to left,
left to right etc.). These are Unicode characters designed to explicitly
specify the direction of otherwise amigious characters.
Ansii does not have, to the best of my knowledge, an equivalent encoded
