Peter's right. Gogorender is one possible solution. It's main
advantage is that it can use any font installed on your computer,
without requiring that it be also installed on your phone (it also
uses Qt's excellent font rendering routines). It's main disadvantage
is that word wrap doesn't always work very well.
Another possibility is to change the Mnemododo font size setting to
"Very Large".
Alternatively, Mnemododo tries to respect the card type formatting
options chosen within Mnemosyne. It may not be able to match the font,
but it should be able to match colours, sizes, and styles.
Yet another possibility is to add a file called STYLE.CSS to the
exported cards directory, and then to add css styling for the
exported cards, e.g.:
div.Mandarin {
font-size: 400%;
}
Where 'Mandarin' is a tag name with any spaces replaced by
underscores. The exported cards also have "div#q" for the question
field, "div#a" for the answer field, and the field names from the card
types, e.g., "div.f" for the foreign word and "div.m_1" for the
meaning (thanks to Peter's Mnemosyne libraries). It may help to open
the CARDS file (read-only!) in a text editor.
If none of these work, I could think about porting the gogostyle
plugin to 2.x:
http://www.mnemosyne-proj.org/old/content/gogostyle
It added special tags around sequences of non-latin characters, so
that they could be styled using the STYLE.CSS mechanism.
