> Before digging into the problem, could you share your impression on whether PostgreSQL can support SJIS? Would it be hopeless? Can't we find any direction to go? Can I find relevant source code by searching specific words like "ASCII", "HIGH_BIT", "\\" etc?
For starters, you could grep "multibyte".
