Junicode implements all characters in this range except for 0340 and 0341, which are deprecated, and 034F for technical reasons. These characters should follow the characters they modify. Combining diacritical marks are seldom very practical in a proportionally spaced font like Junicode, for it is difficult to control their alignment with respect to the characters they modify and those they follow. Junicode now contains advanced typographical features that can help programs to align these diacritics correctly, but currently the only major program that takes advantage of these is Adobe InDesign.
In the following table, combining diacritical marks are mostly displayed with the letter a.
