Problem: It is not easy to count the number of characters.
Solution: Add the skipcc argument to strchars(). (Hirohito Higashi, Ken
Takata)

! strchars({expr}) *strchars()*
The result is a Number, which is the number of characters
! String {expr} occupies. Composing characters are counted
! separately.
Also see |strlen()|, |strdisplaywidth()| and |strwidth()|.
strdisplaywidth({expr}[, {col}]) *strdisplaywidth()*
The result is a Number, which is the number of display cells
! String {expr} occupies on the screen.
When {col} is omitted zero is used. Otherwise it is the
screen column where to start. This matters for Tab
characters.

! strchars({expr} [, {skipcc}]) *strchars()*
The result is a Number, which is the number of characters

! When {skipcc} is omitted or zero, composing characters are
! counted separately.
! When {skipcc} set to 1, Composing characters are ignored.
Also see |strlen()|, |strdisplaywidth()| and |strwidth()|.

The result is a Number, which is the number of display cells

When {col} is omitted zero is used. Otherwise it is the
screen column where to start. This matters for Tab
characters.

*strlen()*
strlen({expr}) The result is a Number, which is the length of the
String
{expr} in bytes.
- If you want to count the number of multi-byte characters (not
- counting composing characters) use something like this: >
-
- :let len = strlen(substitute(str, ".", "x", "g"))
- <
If the argument is a Number it is first converted to a String.
For other types an error is given.
! Also see |len()|, |strchars()|, |strdisplaywidth()| and
! |strwidth()|.
