From e1370f924df65e72843b5f81400230e1c2591485 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Valim?= Date: Fri, 19 May 2017 16:06:08 +0200 Subject: Return error tuple on unicode normalization functions Prior to this patch, the normalization functions in the unicode module would raise a function clause error for non-utf8 binaries. This patch changes it so it returns {error, SoFar, Invalid} as characters_to_binary and characters_to_list does in the unicode module. Note string:next_codepoint/1 and string:next_grapheme had to be changed accordingly and also return an error tuple. --- lib/stdlib/test/string_SUITE.erl | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'lib/stdlib/test/string_SUITE.erl') diff --git a/lib/stdlib/test/string_SUITE.erl b/lib/stdlib/test/string_SUITE.erl index 4320b735ac..90f980c0e5 100644 --- a/lib/stdlib/test/string_SUITE.erl +++ b/lib/stdlib/test/string_SUITE.erl @@ -582,6 +582,8 @@ cd_gc(_) -> [$e,778] = string:next_codepoint([$e,778]), [$e|<<204,138>>] = string:next_codepoint(<<$e,778/utf8>>), [778|_] = string:next_codepoint(tl(string:next_codepoint(<<$e,778/utf8>>))), + [0|<<128,1>>] = string:next_codepoint(<<0,128,1>>), + {error,<<128,1>>} = string:next_codepoint(<<128,1>>), [] = string:next_grapheme(""), [] = string:next_grapheme(<<>>), @@ -589,6 +591,8 @@ cd_gc(_) -> "abcd" = string:next_grapheme("abcd"), [[$e,778]] = string:next_grapheme([$e,778]), [[$e,778]] = string:next_grapheme(<<$e,778/utf8>>), + [0|<<128,1>>] = string:next_grapheme(<<0,128,1>>), + {error,<<128,1>>} = string:next_grapheme(<<128,1>>), ok. -- cgit v1.2.3
