Re: unicode data - accessing codepoints > FFFF on narrow python builts

[vbr at email.cz]

Hi, thanks for your answer,
I'll try to check the source of unicodedata;
Using the wide Unicode build seems to be a kind of overkill for now, as for the vast majority of my uses, the BMP is enough. I was rather looking for some "lower-cost" alternatives for those rare cases, when I need higher multilingual planes.

Thanks again,
