< p >
In the same JAR file as Jskad, power users will find a command-line
2003-05-31 23:17:41 +00:00
utility that converts a Tibetan Machine Web-encoded (TMW-encoded) Rich
2003-06-15 20:27:56 +00:00
Text Format (RTF) file to either of these three output formats:
2003-05-18 15:18:31 +00:00
< / p >
2003-05-31 23:17:41 +00:00
< ul >
2003-06-15 20:27:56 +00:00
< li > RTF files in Unicode< / li >
2003-05-31 23:17:41 +00:00
< li > RTF files with the appropriate THDL Extended Wylie (Wylie) used
instead of TMW< / li >
< li > RTF files in Tibetan Machine (used in legacy systems)< / li >
< / ul >
2003-05-18 15:18:31 +00:00
2003-06-08 22:43:43 +00:00
< p >
In addition, this converter can convert Tibetan Machine RTF files to
2003-06-15 20:27:56 +00:00
Tibetan Machine Web RTF files, and takes precautions to ensure that
only a 100% perfect conversion is done in both directions
(TM-> TMW and TMW> TM). One such precaution is that two
independent teams (Garrett and Garson, Chandler) turned the Tibetan
Machine Web < a
href="http://iris.lib.virginia.edu/tibet/tools/tmw.html#doc">
documentation< / a > into TM< -> TMW tables. These tables
were compared, giving full confidence that the tables are as
accurate as the documentation (which has a < a
href="http://sourceforge.net/tracker/index.php?func=detail& aid=746871& group_id=61934& atid=502515">
few flaws< / a > itself). That documentation has not been
extensively verified against the actual fonts, however.
Another precaution is that any unknown characters cause the
conversion to fail, and the result is a document containing merely
the unknown characters. (There are some known, illegal glyphs
created by Tibet Doc, and the converter handles the ones it knows of
and treats the rest as unknown.)
2003-06-08 22:43:43 +00:00
< / p >
2003-05-18 15:18:31 +00:00
< p >
This converter is smart enough to solve the " curly-brace
2003-06-15 20:27:56 +00:00
problem" , wherein Tahoma '{', '}', and '\' characters appear
instead of the TMW stacks they are supposed to represent. This
problem originates with certain versions of Microsoft Word's Rich
Text Format writing capabilities.
2003-05-18 15:18:31 +00:00
< / p >
< p >
Further, this converter gives a polite error message when a given
.rtf file simply cannot be read by the version of Java used.
< / p >
< p >
Perhaps most importantly, the converter has a
< tt > --find-some-non-tmw< / tt > mode of operation that gives you, the
user, confidence that RTF reading and writing idiosyncrasies are not
going to interfere with a flawless conversion. It does so by
printing out the first occurrence of a given character in a non-TMW
font. Here is some example output:
< / p >
< pre >
java -cp Jskad.jar \
2003-06-15 20:27:56 +00:00
org.thdl.tib.input.TibetanConverter \
2003-05-18 15:18:31 +00:00
--find-some-non-tmw \
"Dalai Lama Fifth History 01.rtf"
non-TMW character newline in the font Tahoma appears first at location 39
non-TMW character ' ' in the font TimesNewRoman appears first at location 45
non-TMW character '}' in the font Tahoma appears first at location 66
non-TMW character '{' in the font Tahoma appears first at location 219
non-TMW character '\' in the font Tahoma appears first at location 1237
non-TMW character newline in the font Times New Roman appears first at location 9754
< / pre >
< p >
Given the above output, you can be sure that a flawless conversion
(barring the appearance of < a href = "#knownbugs" > known bugs< / a > ) will
result when you run < tt > java -cp Jskad.jar
2003-06-15 20:27:56 +00:00
org.thdl.tib.input.TibetanConverter --to-wylie "Dalai Lama
2003-05-31 23:17:41 +00:00
Fifth History 01.rtf" > "Dalai Lama Fifth History 01 in THDL
Extended Wylie.rtf"< / tt > . This is because the only text in the
input file besides Tibetan is whitespace and the Tahoma characters
2003-05-18 15:18:31 +00:00
< tt > '{'< / tt > , < tt > '}'< / tt > , and < tt > '\'< / tt > . These Tahoma
characters are understood by the tool; they are symptoms of the
" curly-brace problem" .
< / p >

< h3 > Failed Conversions< / h3 >
< p >
In this section, you'll learn how to tell if a conversion has
succeeded in full, ran into minor problems, or failed altogether.
< / p >
< h4 > TMW to Wylie< / h4 >
2003-05-18 17:18:27 +00:00
< p >
Note that some TMW glyphs have no transliteration in Exteded
Wylie. When you encounter such a glyph, you'll find a message
like the following in your RTF output:
< / p >
< p >
< tt > < < [[JSKAD_TMW_TO_WYLIE_ERROR_NO_SUCH_WYLIE: Cannot convert
DuffCode < duffcode font=TibetanMachineWeb8 charNum=101
character=e/> to THDL Extended Wylie. Please see the < a
href="http://iris.lib.virginia.edu/tibet/tools/tmw.html#doc">
documentation for the TMW font< / a > and transcribe this
yourself.]]> > < / tt >
< / p >
< p >
Upon seeing this, you should consult the < a
href="http://iris.lib.virginia.edu/tibet/tools/tmw.html#doc">
documentation< / a > for the specific TMW font named. Find the
glyph (by its charNum) and decide how to proceed. If you find
a glyph that you believe should have been converted into Extended
Wylie by the tool, please report this as a bug.
< / p >
2003-06-15 20:27:56 +00:00
< h4 > Other Conversions< / h4 >
< p >
The other conversions are all-or-nothing. That is, if you run
into any trouble whatsoever, the result will be a file containing
just the problematic glyphs. If your result is as long as your
input, then the conversion went flawlessly.
< / p >
< p >
There is one TMW glyph (TibetanMachineWeb7, glyph 91) that has no
Tibetan Machine equivalent. This glyph is the only TMW glyph
that can cause a TMW-> TM conversion to fail.
< / p >
< p >
You might consider using Jskad to convert documents that give
errors, as it has better error reporting and can tell you just
what's wrong.
< / p >
2003-05-31 23:17:41 +00:00
< p >
2003-06-15 20:27:56 +00:00
If you ever encounter problems in a TM-> TMW conversion, please
send us mail with the error report (and the problem input document's
resulting document) so that we can improve our tools.

2003-05-18 15:18:31 +00:00
< h3 > Invoking the Converter< / h3 >
< p >
First add Jskad.jar to your CLASSPATH. Now run the command
2003-06-15 20:27:56 +00:00
< tt > java org.thdl.tib.input.TibetanConverter< / tt > from a
command prompt. You will see usage information appear.
2003-05-18 15:18:31 +00:00
< / p >
< h3 > < a name = "knownbugs" > < / a > Known Bugs< / h3 >
< p >
If the TMW given is not syntactically legal, then the Wylie that
results will not necessarily yield, if imported into Jskad, the same
2003-06-15 20:27:56 +00:00
Tibetan with which the converter started. The glyphs
corresponding to the Wylie 'jaskadaskeda' have this problem, for
example.
