intended for use on DOS and Mac systems. It is a rearrangement of ArmSCII-8, to work with existing DOS and Mac code that reserve a range of code values for characters not intended for text but for presentation layout, using modified fonts; it is, however, considered as a "hack" of the code pages over which it is applied, as neither DOS (nor Windows in the "OEM" compatibility codepages used by the text-only console) nor MacOS has ever supported this encoding natively, notably in their file system (but this is also true for the now deprecated ISO 10585 standard). However, this encoding cannot map all the punctuation characters normally needed for Armenian, so the missing characters must be approximated using fallbacks to ASCII punctuation (some Armenian fonts may display these ASCII punctuation using the rendering intended for the Armenian characters that are mapped to them by these fallbacks). ArmSCII-7 In this table, code value 21 is the eternity sign, which has, since 2013, a designated point in Unicode U+058E (LEFT-FACING ARMENIAN ETERNITY SIGN) and another for its right-facing variant: U+058D (RIGHT-FACING ARMENIAN ETERNITY SIGN). Some mappings incorrectly claim that it has a code point of U+0530. Code value 20 is the regular SPACE character; code values 00–1F and 7F are not assigned to characters by AST 34.005, though they may be the same as the ASCII control characters that are located in those positions. Code value 22 is used to encode the Armenian ligature ew (և). In some variants, it encodes the section sign (§) instead. It is strongly suggested to encode this ligature with the normal Armenian ech (yech) and yiwn (vyun) small letters pair, as various software or fonts will render it differently depending on the version of ArmSCII-7 they are assuming, and so let the renderer generate the ligature. Code value 7F may be used sometimes as a substitution for the non-breaking space. Note that the characters encoded at code values 2D and 7E (Armenian hyphen and apostrophe) may not be visible with all fonts supporting Armenian. This table is simply remapped to higher codes by simple offset in ArmSCII-8 (below). ArmSCII-8 In this table, code value 20 is reserved for the regular SPACE character, code value A0 is reserved for the non-breaking space, and code value A1 is assigned to the eternity sign, which has, since 2013, a designated point in Unicode U+58E (LEFT-FACING ARMENIAN ETERNITY SIGN)
