## Function Documentation

## ◆ appendOrFFFD()

template<typename StringClass >

StringClass& U_HEADER_ONLY_NAMESPACE::utfstring::appendOrFFFD | ( | StringClass & | s,
|  | UChar32 | c
| ) |  |
| inline

Appends the code point to the string.

Appends the U+FFFD replacement character instead if c is not a scalar value. See https://www.unicode.org/glossary/#unicode_scalar_value

Template Parameters

  StringClass | A version of std::basic_string (or a compatible type)

Parameters

  s | The string to append to
  c | The code point to append

Returns
  s

Draft:
  This API may be changed in the future versions and was introduced in ICU 78

## ◆ appendUnsafe()

template<typename StringClass >

StringClass& U_HEADER_ONLY_NAMESPACE::utfstring::appendUnsafe | ( | StringClass & | s,
|  | UChar32 | c
| ) |  |
| inline

Appends the code point to the string.

The code point must be a scalar value; otherwise the behavior is undefined. See https://www.unicode.org/glossary/#unicode_scalar_value

Template Parameters

  StringClass | A version of std::basic_string (or a compatible type)

Parameters

  s | The string to append to
  c | The code point to append (must be a scalar value)

Returns
  s

## ◆ encodeOrFFFD()

template<typename StringClass >

StringClass U_HEADER_ONLY_NAMESPACE::utfstring::encodeOrFFFD | ( | UChar32 | c | ) |
| inline

Returns the code point as a string of code units.

Returns the U+FFFD replacement character instead if c is not a scalar value. See https://www.unicode.org/glossary/#unicode_scalar_value

Template Parameters

  StringClass | A version of std::basic_string (or a compatible type)

Parameters

  c | The code point

Returns
  the string of c's code units

## ◆ encodeUnsafe()

template<typename StringClass >

StringClass U_HEADER_ONLY_NAMESPACE::utfstring::encodeUnsafe | ( | UChar32 | c | ) |
| inline

Returns the code point as a string of code units.

The code point must be a scalar value; otherwise the behavior is undefined. See https://www.unicode.org/glossary/#unicode_scalar_value

Template Parameters

  StringClass | A version of std::basic_string (or a compatible type)

Parameters

  c | The code point

Returns
  the string of c's code units
