    Thanks for the information. In fact I want to use my language Bengali for
    sending and receiving SMS in my mobile phone. Even if that is not Unicode,
    initially it will not be a problem. When we started writing Bengali we
    created Fonts (By changing the shape of the Latin Characters) and Keyboard
    drivers ( To create lot more characters than English) and even today 99%
    people use ASCII based Bengali fonts and keyboard systems for writing
    Bengali in computers.Only very recently we are having Unicode under WInXP.
    But that is also with limited support. The applications which are Unicode
    aware-does not suppport Bengali. MS Office is the only exception.
    For mobile phone, I want to have the same solution like ASCII based Bangla.
    Can you let me know how I can install a TrueType Font in a mobile phone and
    how I can create a keyboard driver for mobile phone? What are the programs
    that is used for creating mobile applications?
    I know Win CE supports TrueType Fonts. But what about mobile windows or
    other os?
    I personally feel that people will be using that mothertongue in mobile
    phones if they can and that should be one of the marketing issue by the
    mobile operators.
    Thanks and regards

    The Treo 600 (and 650) use Palm OS 5. This has some limited support
    for conversion between the device character encoding (typically
    CP1252) and various flavors of Unicode, but is not Unicode under the

    If it receives email or SMS that's been encoded using Unicode
    (typically UTF-8 and UCS-2, respectively) then the built-in
    applications should attempt conversion to CP1252, with the expected
    loss of data for unsupported characters.

    Most are Unicode-aware, in that I believe most support UCS-2 encoded
    SMS and UTF-8 encoded email. The level of support for UTF-8 in
    vObjects (typically for beaming addresses) varies more, with several
    phones ignoring the charset tag for inbound data and/or setting the
    charset incorrectly on outbound vObjects.

    Note that Unicode-aware and Unicode-under-the-hood are different
    questions. You could argue that the Treo 600 is Unicode aware, but
    because it doesn't use Unicode for the device character set, support
    for displaying additional languages such as Bengali and N'ko is very
    limited, and would typically require applications to hack up their
    own (limited) solution.

    In addition, even though an increasing number of mobile devices use
    Unicode as the base encoding, the font/layout/rendering support code
    would also need to handle the target languages. And you'd need some
    way of installing additional fonts, which is often a problem on
    mobile devices, since carriers aren't very excited about allowing
    users to easily extend the OS.
