2 Using Unicode in Erlang

2.1 Unicode Implementation

Implementing support for Unicode character sets is an ongoing process. The Erlang Enhancement Proposal (EEP) 10 outlined the basics of Unicode support and also specified a default encoding in binaries that all Unicode-aware modules should handle in the future.

The functionality described in EEP10 was implemented in Erlang/OTP R13A, but that was by no means the end of it. In Erlang/OTP R14B01 support for Unicode file names was added, although it was in no way complete and was by default disabled on platforms where no guarantee was given for the file name encoding. With Erlang/OTP R16A came support for UTF-8 encoded source code, among with enhancements to many of the applications to support both Unicode encoded file names as well as support for UTF-8 encoded files in several circumstances. Most notable is the support for UTF-8 in files read by file:consult/1登录查看完整内容
