ox-ascii: Convert `length' to `string-width'
* lisp/ox-ascii.el (org-ascii--current-text-width): Convert `length' to `string-width'. (org-ascii--build-title, org-ascii--build-toc) (org-ascii--list-listings, org-ascii--list-tables) (org-ascii-template--document-title) (org-ascii-inner-template, org-ascii-format-inlinetask-default) (org-ascii-format-inlinetask-default, org-ascii-item (org-ascii--table-cell-width, org-ascii-table-cell) (org-ascii--current-text-width): Likewise. I've checked all occurrences of the function `length' in ox-ascii.el. It turns out that the most of them are calculating the width of given string. To support fullwidth characters, we better use `string-width' instead of `length'. Some characters in UCS are categorized as "East Asian Ambiguous"[1]. The return value of `string-width' with those characters depends on how Emacs is setup. We leave those ambiguous character handling to Emacs. Two usages of `length' in `ox-ascii.el' were left as-is, because those were used for: - bullet depth calculation in `org-ascii-headline', and - cell position calculation in `org-ascii--table-cell-width'.
