My solution is that I have a custom tag, and the internal processing code
looks something like this:
.rtlclass {font-family:David,arial;font-size:12px;direction:rtl}
if (isRTL(myStr)) {
out.append("<span class='rtlclass'>‏");
out.append(myStr);
out.append("‏</span>");
}
public static final boolean isRTL(final String str) {
for (int i = 0; i < 3; i++) {
if (str.length() == i)
return false;
Character.UnicodeBlock block = Character.UnicodeBlock.of(str.charAt(i));
if (block == Character.UnicodeBlock.ARABIC ||
block == Character.UnicodeBlock.ARABIC_PRESENTATION_FORMS_A ||
block == Character.UnicodeBlock.ARABIC_PRESENTATION_FORMS_B ||
block == Character.UnicodeBlock.HEBREW)
{
return true;
}
}
return false;
}
The "‏" on both sides is important because otherwise the browser *will*
screw up if you have punctuation at the end of the string.
Another thing to note is that, for some reason, all browsers tend to render
non-Latin fonts in a very teensy size. I don't know why. So it's a good
idea to have code to make sure that rtlclass has a bigger fontsize than you
would normally use.
