2.1.87 Part 1 Section 17.3.2.26, rFonts (Run Fonts)

a.   The standard does not limit the length of the ascii, hAnsi, cs, and eastAsia attributes.

Word restricts the value of these attributes to be less than 32 characters.

b.   The standard states that the use of each of the run fonts shall be determined by the Unicode character values of the run content, but does not explain precisely how this is done.

Word determines the use of each of these fonts from the Unicode character values in the following manner:

  • If the run has the cs element ("[ISO/IEC-29500-1] §17.3.2.7; cs") or the rtl element ("[ISO/IEC-29500-1] §17.3.2.30; rtl"), then the cs (or cstheme if defined) font is used, regardless of the Unicode character values of the run’s content.

  • If the eastAsia (or eastAsiaTheme if defined) attribute’s value is “Times New Roman” and the ascii (or asciiTheme if defined) and hAnsi (or hAnsiTheme if defined) attributes are equal, then the ascii (or asciiTheme if defined) font is used.

  • Otherwise, the following table is used. For all ranges not listed in the following table, the hAnsi (or hAnsiTheme if defined) font shall be used.

c.   The standard states that the default fonts for the ascii, hAnsi, cs, and eastAsia attributes are application-defined.

Word uses a default font of Times New Roman for all of these attributes.

d.   The standard states that all characters that are determined to be East Asian should use the value of eastAsia element as the font.

If the value of eastAsia attibute is "Times New Roman", and the value of the ascii (or asciiTheme) and the hAnsi (or hAnsiTheme) attributes are equal, then the value of the ascii (or asciiTheme, if defined) attribute is used as the font.

e.   The standard states the following regarding ascii and asciiTheme attributes: If the asciiTheme attribute is also specified, then this attribute (ascii) shall be ignored and that value shall be used instead. If the ascii attribute is also specified, then that attribute (asciiTheme) shall be ignored and this value shall be used instead.

These statements only apply to the current rFonts element that both attributes appear in and are not taken into consideration at different levels of the style hierarchy.

If an inherited style contains an rFonts element with the ascii attribute it will override any previously specified ascii or asciiTheme attribute in the style hierarchy. The same is true of the asciiTheme attribute, it will also override any previously specified asciiTheme or ascii attribute in the style hierarchy.

Similar behavior exists for cs, csTheme, eastAsia, easAsiaTheme, hAnsi, and hAnsiTheme attributes.
