I know the combining diacritical marks approach.
The only problem I have is the inconsistency with the other 2 mentioned
characters (4, if caps considered).
A keyboard can generate a single or combined character in few different
1. direct character generation; useful for base characters or
frequently used composed characters, not recommended for rarely used
2. dead key mechanism; useful for composed characters that happen to be
used occasionally on a given language or conjuncture
3. ligatures; I know that this is technically possible, however, I am
not aware of an European language that actually uses this mechanism
As far as I know, the target of (1) and (2) should be a single point
character, whereas the target of (3) should be a string of n
characters. Feel free to correct me on this.
In my case (keyboard definition) I either should
a) keep the actual keyboard structure and extend the existing
characters 1EA4, 1EA5, 1EAE and 1EAF with ?? (reason of this thread)
b) ignore the existing 1EA4, 1EA5, 1EAE and 1EAF characters and extend
the keyboard with 6 ligatures
Additional question - if so, then what was the reason for the existing
1EA4, 1EA5, 1EAE and 1EAF characters ? Are those characters used on a
regular basis in Vietnamese language ?
Thank you for your link and sample.
I will keep this for future reference; however, in this case I am
referring to the principle and not to an occasional need to write
