// NEXT LINE (NEL, 0x85) character is special in that some Unicode versions do
|
|
// not include it as a whitespace character.
|
|
//
|
|
// However all Dart backends handle it as a whitespace character. dart2js and
|
|
// dart2wasm do this by a calling JS (`String.prototype.trim` and its
|
|
// left/right variants) and doing post-processing. To check these
|
|
// implementations tests in this file mix the SPACE character with NEL in
|
|
// various positions.
|
|
//
|
|
// string_trim_lr_test.dart tests various NEL characters on the left and right,
|
|
// but they do not mix NEL with other whitespace characters.
|
|
// string_trim_test.dart tests do not test NEL.
