Corpus alignment for Arabic and English

I'm wondering if Bleualign can be used for corpus alignment of Arabic and English texts? Or will the fact that Arabic is read from right to left affect performance?

Bleualign will work fine for Arabic-English - only languages that don't segment words with space symbols are a theoretical problem for BLEU with default settings, but you can use --bleu_charlevel for these to perform character-level BLEU.
