Version 1.0.0 (2022-08-07)

  • Replace error types InvalidUtf8Array, InvalidUtf8Slice, InvalidUtf8FirstByte and InvalidUtf8 with Utf8Error plus Utf8ErrorKind.
    Which of the new error kind variants is reported don't map 1:1 to the old enum variants: For example Utf8ErrorKind::NonUtf8Byte is returned for sequences that would previously have been reported as too high codepoint or overlong encoding.
  • Rename many other error types for consistency:
    • InvalidCodepoint -> CodepointError
    • InvalidUtf16FirstUnit -> Utf16FirstUnitError
    • InvalidUtf16Array -> Utf16ArrayError
    • InvalidUtf16Slice -> Utf16SliceError
    • 1InvalidUtf16Tuple -> Utf16TupleError
  • Change return type of CodepointError::error_range() to RangeInclusive.
  • Rename some errors variants:
    • Utf16SliceError::FirstLowSurrogate -> FirstIsTrailingSurrogate
    • Utf16SliceError::SecondNotLowSurrogate -> SecondIsNotTrailingSurrogate
    • Utf16TupleError::InvalidSecond -> SecondIsNotTrailingSurrogate
  • Expose the error type of Utf16Char::from_bmp() and rename it to NonBmpError.
  • Remove re-exports of Utf8CharIterator and Utf16CharIterator from the crate root.
    (They are still exposed via the iterator module.)
  • Remove impls of the deprecated AsciiExt trait, and make the methods available in #![no_std]-mode.
  • Make many of the previously AsciiExt methods take self by value.
  • Drop support for pre-1.0 versions of the ascii crate.
  • Remove iter_bytes() and iter_units().
  • Increase minimum Rust version to 1.56 and change the minimum Rust version policy.
  • Fix possible UB or panic in Utf8Char::from_slice_start_unchecked() when passed an empty slice.
    (relates to #12.)
  • Make many methods const fn.
  • Add const fns Utf8Char::new() and Utf16Char::new().

Version 0.3.6 (2019-08-23)

  • Fix pointless undefined behavior in Utf16Char.to_ascii_char() (which is part of ascii feature)
  • Widen ascii version requirement to include 1.*.
  • Add [u16; 2] UTF-16 array alternatives to (u16, Some(u16)) UTF-16 tuple methods.
  • Add Utf16Char.is_bmp().

Version 0.3.5 (2018-10-23)

  • Fix docs.rs build failure

Version 0.3.4 (2018-10-23)

  • Fix UB in UTF-8 validation which lead to invalid codepoints being accepted in release mode.
  • Add fallible decoding iterator adapters Utf8CharMerger and Utf16CharMerger and slice-based iterators Utf8CharDecoder and Utf16CharDecoder
  • Widen ascii version requirement from 0.8.* to 0.8.0 - 0.10.*
  • Implement creating / extending Strings from Utf16Char-producing iterators

Version 0.3.3 (2018-10-16)

  • Fix UTF-8 overlong check. (from_array() and from_slice() accepted two-byte encodings of ASCII characters >= '@', which includes all letters)
  • Implement FromStr for Utf16Char
  • Add from_str_start() to Utf8Char and Utf16Char
  • Add Utf{8,16}Char{s,Indices}: str-based iterators for Utf8Char and Utf16Char equivalent to char's Chars and CharIndices.
  • Add StrExt with functions to create the above iterators.
  • Implement FromIterator and Extend for Vec<{u8,u16}> with reference-producing Utf{8,16}Char iterators too.
  • Add Utf8CharSplitter and Utf16CharSplitter: Utf{8,16}Char-to-u{8,16} iterator adapters.
  • Add IterExt, iter_bytes() and iter_units() to create the above splitting iterators.
  • Add Utf8Char::from_ascii(), Utf16Char::from_bmp() with _unchecked versions of both.
  • Add cross-type PartialEq and PartialOrd implementations.
  • Change the description() for a few error types.

Version 0.3.2 (2018-08-08)

  • Hide AsciiExt deprecation warning and add replacement methods.
  • Correct documentation for U8UtfExt::extra_utf8_bytes().
  • Fix misspellings in some error descriptions.
  • Avoid potentially bad transmutes.

Version 0.3.1 (2017-06-16)

  • Implement Display for Utf8Char and Utf16Char.

Version 0.3.0 (2017-03-29)

  • Replace the "no_std" feature with opt-out "std".
    • Upgrade ascii to v0.8.
    • Make tests compile on stable.
  • Remove CharExt::write_utf{8,16}() because encode_utf{8,16}() has been stabilized.
  • Return a proper error from U16UtfExt::utf16_needs_extra_unit() instead of None.
  • Rename U16UtfExt::utf_is_leading_surrogate() to is_utf16_leading_surrogate().
  • Rename Utf16Char::from_slice() to from_slice_start() and CharExt::from_utf{8,16}_slice() to from_utf{8,16}_slice_start() to be consistent with Utf8Char.
  • Fix a bug where CharExt::from_slice() would accept some trailing surrogates as standalone codepoints.

Version 0.2.0 (2016-07-24)

  • Change CharExt::write_utf{8,16}() to panic instead of returning None if the slice is too short.
  • Fix bug where CharExt::write_utf8() and Utf8Char::to_slice() could change bytes it shouldn't.
  • Rename lots of errors with search and replace:
    • CodePoint -> Codepoint
    • Several -> Multiple
  • Update the ascii feature to use ascii v0.7.
  • Support #[no_std]; see 70e090ee for differences.
  • Ungate impls of AsciiExt. (doesn't require ascii or nightly)
  • Make the tests compile (and pass) again. (They still require nightly).

Version 0.1.* (2016-04-07)

First release.
