comparison between DejaVu and correct Lao fonts
In Lao script, there are vowels that are written on top of consonants and tone
markers which are written on top of consonants as well. In the case that a
consonant contains a top vowel and a tone marker, the tone marker should be
placed a little bit higher because it is otherwise displayed at the same
position where the vowel is shown. If it is not done, it could get impossible
to read/understand the word (although I do not have an example because I am no
native speaker in Lao language).
DejaVu includes the lao characters but does not take into account the problem
that I have explained above. I am running a Ubuntu without special
configurations in my fonts and it seems to me that DejaVu is more or less the
only font that supports Lao characters in a default installation. Therefore, it
is the fallback-font for nearly every text written in Lao language.
To clarify the problem that occurs, I have written a short piece of text which
compares the result of Lao script for DejaVu and two Lao fonts (Phethsarath and
Saysettha). So the result should look more or less like the one that
Phethsarath and Saysettha produce.
Thai language/script, which is very similar to Lao, has the same "feature". By
default, it works in an Ubuntu installation. Maybe, it is possible to get the
idea how to implement this behaviour by inspecting a free Thai font?
If there are any more questions or if I could help with further information
regarding Lao script, please feel free to contact me.</pre>
