[Haskell-cafe] Re: String vs ByteString

Hi Don, With respect, I disagree with that approach. Almost every modern programming language has one or at most two standard representations for strings. That includes PHP, Python, Ruby, Perl and many others. The lack of a standard text representation in Haskell has created a crazy patchwork of incompatible libraries requiring explicit and often inefficient conversions to connect them together. I expect Haskell to be higher level than those other languages so that I can ignore the lower level details and focus on the algorithms. But in fact the string issue forces me to deal with lower level details than even PHP requires. I end up with a program littered with ugly pack, unpack, toString, fromString and similar calls. That just doesn't feel right to me. Kevin On Aug 13, 10:39 pm, Don Stewart wrote:

I find it disturbing that a modern programming language like Haskell still apparently forces you to choose between a representation for "mostly ASCII text" and Unicode.

Surely efficient Unicode text should always be the default? And if the Unicode format used by the Text library is not efficient enough then can't that be fixed?

Here's a rule of thumb: If you have binary data, use Data.ByteString. If you have text, use Data.Text.

If you have a large amount of mostly ASCII text, use ByteString, since Data.Text uses twice the storage. �Also, ByteString might make more sense if the data is in a byte-oriented encoding, and the cost of encoding and decoding utf-16 would be significant.
