[erlang-questions] unicode + version < 17.0
Thu Apr 17 17:07:56 CEST 2014
I have a library where the input to the function should be given as utf8.
Inputs can be:
or sometimes <<"http://www.詹姆斯.com/atomtests/iri/<http://www.xn--8ws00zhy3a.com/atomtests/iri/>
The library I am using should be compatible with the Erlang R15 to 17.0
versions and I wonder if there is a graceful way to handle inputs
depending on the Erlang version
>From a discussion on IRC, I found I can easily convert a string to unicode
using the following function:
UnicodeURL = case unicode:characters_to_binary(URL, InEnc) of
URL1 when is_binary(URL1) ->
It also works on R16B if I set the source code encoding with the file
header `%% -*- coding: utf-8 -*-`.
But how to handle it when the source code encoding is latin1? How to handle
it in version < R16B? Is this possible?
If not, can we disable functions depending of an Erlang version in a module?
Any help is appreciated :)
