It may be reduced to 20 code points if converted to NFC.
Some abstract characters can be encoded by different code points;
We think that the importance of code points is frequently overstated.
Code points do not occupy one column even in monospace fonts and terminals.
Counting coded characters or code points is important.
Most Unicode code points take the same number of bytes in UTF-8 and in UTF-16.
In both UTF-8 and UTF-16 encodings, code points may take up to 4 bytes.
Even though the code points of UTF-8 and ANSI are pretty much identical, older operating systems like Windows 95 cannot work with it.
It is true that we can count code units and code points in constant time in UTF-32.
Graphemes, code units, code points and other relevant Unicode terms are explained in Section 5.
In 1991,the first version of the Unicode standard was published, with code points limited to 16 bits.
Yet, the number of code points in it is irrelevant to almost any software engineering task, with perhaps the only exception of converting the string to UTF-32.
Indexing operations wouldbe counting code units rather than the code points, as they in fact did before the change.
For example, the NFD string from the example above, which consists of three real words in three real languages,will consist of 20 code points in NFC.
Surragates, noncharacters and unassigned code points do not correspond to abstract characters at all.
As we already noted, there is a popular idea that counting, splitting,indexing or otherwise iterating over code points in a Unicode string should be considered a frequent and important operation.
We see no particular reason to favor Unicode code points over Unicode grapheme clusters,code units or perhaps even words in a language for that.
Here is an excerpt of the definitions regarding characters, code points, code units and grapheme clusters according to the Unicode Standard with our comments.
Working with a variable length encoding,where ASCII-inherited code points are shorter than other code points may seem like a difficult task, because encoded character boundaries within the string are not immediately known.
In NFC each code point corresponds to one user-perceived character.
Then select codes points.
In both encodings, the code units of multi-part encoded code point will have MSB set to 1.
Also, you can search for a non-ASCII, UTF-8 encoded substring in a UTF-8 string as if it was a plain byte array-there is no need to mind code point boundaries.
The reason why ANSI cannot accommodate is ituses only 8 bits to represent every code point.
This is thanks to another design feature of UTF-8- a leading byte of an encoded code point can never hold valuecorresponding to one of trailing bytes of any other code point.
Some abstract characters cannot be encoded by a single code point.
The UNICODE() function returns a unicode code point for the first character in a text string.
The abstract characterǵ can be coded by the single code point U+01F5 latin small letter g with acute, or by the sequence.
A character not on the keyboard canbe entered into Wordpad by typing its hexadecimal code point in Unicode followed by Alt+X. Likewise, the code point of a character from another application can be determined by copying it into Wordpad followed by Alt+X.
The above code point will be encoded as four code units‘f0 b2 90 bf' in UTF-8, two code units‘d889 dc3f' in UTF-16 and as a single code unit‘0003243f' in UTF-32.
