Nepali Fonts Standard

Nepal Codes for Information Interchange White Paper v2 Font Standardisation Working Committee, 1997 page 16 is also important to decide on basic widths for characters in reference to the vertical stem eventhough some characters will not have a stem. For standard TTF fonts these numbers in Fontographer may be: Ascent height : 2000 Descent height : -500 Bar height : 1300 Minimum width : 700 Maximum width : 2000 Underline height : -300 Right offset for right aligned : 200 Right offset for center aligned : 600 With these measurements the '/' character would be 1300 tall and around 1600 wide with the vertical stem at 600 from the right 'width' line or at 1000 from the left edge. This means the base of the ' Ù ' would start 600 left of the zero line for center aligned and 200 left of the zero line for right aligned characters. The need for two sets of diacritics is for this reason that some characters have the vertical stem in the middle and some have it on the left edge. A list is given below of special characters which need to be drawn with a specific measurement in mind. This drawing shows the measurements which need to be planned before starting to draw the font characters. Use the table to plan it carefully. The 'Origin' of the character is the bottom left corner so 'H' measures to the right from the Origin and 'D' measures up from the origin. Label Center aligned character / Right aligned character 8 Description A 60 60 slant on top bar can be square or slanted B 60 60 slant on top bar - same as A C 130 130 top bar thickness C+D 1300 1300 C+D : is height of character E 650 650 height of half 'r' Ã F 700 300 diacritics align on F and G measurements G 830 430 alignment edge for diacritics and vertical stem. This is one of the most important G-F 130 130 width of vertical stem H 1600 900 width of character - top bar should extend 5 points beyond this measurement Note: all numbers are given in co ordinates of : (horizontal), (vertical) where the bottom left corner is taken as 0,0 There are a number of groups of characters which need to be dealt with consistently in all fonts so that the characters and diacritics will align properly. Otherwise if one font wants the Z to be center aligned and another wants it right aligned then changing fonts will cause the diacritics to be missaligned and there will again be a problem. This problem will only be for the TTF fonts since in Unicode there is the possibility to program into the font how to align the diacritics over the consonants. Here are the sets of characters to plan for:
