in reply to Something is wrong with this pattern

The value inside $operator (supposed to "." in case of "11.5") is interpreted as special character inside regular expression. Escape its special meaning as following

$celldata=~m{(.+?)\Q$operator\E(.*)}

You can better use split for this if you have only one "$operator" in a string

($left_str, $right_str) = split(/\Q$operator\E/, $celldata);

[ELISHEVA]: Simple yes. and I did consider that. but this isn't one off . An important data source that I don't control is generating bom prefixed utf8 files and I'd rather not have to be munging files every few months.
[erix]: on teh other hand a SOPW is pretty much garanteed to get an answer from tux (and probably the module fixed)
[ELISHEVA]: plus it bugs me that something that *should* be simple, *should* work- unicode and noms aren't exactly the new kids on the block
[ELISHEVA]: well then since the obvious possible mistakes on my part have been ruled out, SOPW it is.
[ELISHEVA]: the data source, or one of them, is the OECD - they provide a *lot* of data that ought to be easily available to perl programmers.
[erix]: it might be cunning to mention the module in the title... :)
[ELISHEVA]: fancy that - a title that actually describes the problem :-)
[ELISHEVA]: but actually thanks for the reminder
[Discipulus]: DBI::CSV + utf8 = BOO?M
[erix]: in extremis we tend to forget stuff ;)
