Char.ConvertToUtf32 Method (Char, Char)
Converts the value of a UTF-16 encoded surrogate pair into a Unicode code point.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.Char
A high surrogate code unit (that is, a code unit ranging from U+D800 through U+DBFF).
- Type: System.Char
A low surrogate code unit (that is, a code unit ranging from U+DC00 through U+DFFF).
Return ValueType: System.Int32
The 21-bit Unicode code point represented by the highSurrogate and lowSurrogate parameters.
highSurrogate is not in the range U+D800 through U+DBFF, or lowSurrogate is not in the range U+DC00 through U+DFFF.
Use this method to convert a surrogate pair into a 21-bit Unicode code point. To convert UTF-16 data into UTF-32 data, use the System.Text.UTF32Encoding class.
Ordinarily, UTF-16 encoding represents a single Unicode character as a 16-bit code unit. However, it also supports surrogate pairs, which allow a single abstract character to be represented as two 16-bit code units. These two Char objects must have code units that range from U+D800 to U+DBFF for the first (high) surrogate and from U+DC00 to U+DFFF for the second (low) surrogate. Surrogate pairs are supported only by UTF-16 encoding. This method allows a character represented by a UTF-16 surrogate pair to be converted to a character using UTF-32 encoding.
