Module:Convert character width

-- This module converts support characters from half-width to full-width, and vice versa. -- See Halfwidth and fullwidth forms for an explanation of half- and full-width characters.

-- @todo FIXME: Needs more characters adding, needs support for diacritic marks.

-- Converts one half-width character to one full-width character. local function getFull( s ) return data[ s ] or s end

-- Converts one full-width character to one half-width character. local function getHalf( s ) for half, full in pairs( data ) do       if s == full then return half end end return s end

-- Converts multiple half-width characters to full-width characters. function p.full( frame ) local s = type( frame ) == 'table' and frame.args and frame.args[ 1 ] or frame s = type( s ) == 'number' and tostring( s ) or s   if type( s ) ~= 'string' then return end return ( mw.ustring.gsub( s, '.', getFull ) ) end
