U+070F Syriac Abbreviation Mark
U+070F was added in Unicode version 3.0 in 1999. It belongs to the block
This character is a Format and is mainly used in the Syriac script. The character is also known as SAM.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as Arabic letter from right to left. When changing direction it is not mirrored. The word that U+070F forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
The Syriac Abbreviation Mark is a Unicode Control character (U+070F) that forms part of the Syriac script block. In Syriac, words are sometimes written in an abbreviated form, omitting some of the last letters. In such cases, a special overline is drawn over some of the final letters of the abbreviated word. Traditionally, this overline has a point at each edge and a point in the middle, but sometimes a plain overline was used. Another use of this overline is to mark numbers: in Syriac numbers are written using numerical values which are assigned to letters (similarly to the Gematria system in Hebrew). The sequence of letters used to write the number are also marked by the overline.
To implement this special overline in Unicode, a special control character was conceived: the Syriac Abbreviation Mark (or SAM), described in section 9.3 of the Unicode Standard. It is inserted in the stream of characters just before the first letter which should be marked with the overline (visually, to the right of it, since Syriac is a right-to-left script). OpenType also has
stch
“feature tag” to pave the way of proper rendering. The rendering engine should put an overline on all subsequent Syriac script letters, until the first character which is not a Syriac letter or diacritic. However, several computer environments do not render this character correctly, but show rather a substitution glyph where it appears in the character stream.Here is an example containing the SAM, just after the Syriac letter Alaph (first letter to the right): ܐܒܓܕ
