They calculate the total width of a string based on "east asian width" property, which is still valid to give a rough measurement of the rendered string. > >>> mb_output_handler - shouldn't setting the proper encoding in 6 do the >>> same job? >>> mb_convert_encoding - don't we already have a number of functions that do >>> encoding conversions? >> >> I don't think It can gracefully handle characters that have no >> corresponding entries in the target character set.

I guess it isn't what I want. If my understanding is correct, a handler set by unicode_set_error_handler() merely deals with the aftermath and cannot interact with the converter. There are good reasons to support user-supplied mappings of characters in PUA to one of legacy encodings such as Shift_JIS, not just replacing such characters by placeholders. In addition to these, shouldn't there be any case where one have to manipulate Unicode strings on per-coded-character-basis rather than per-grapheme-basis just like substr() in PHP6?
