At the TR.30.1 meeting in Arlington, VA we discussed the conversion of
5-bit Baudot to T.140/ISO 10646. Basically, we came to the same
conclusion as Gunnar describes below. However, the simple padding of 0's
does not work for characters such as a carriage return, does it? Of
course, there are several characters in the T.140 ISO 10646-1
Basic/Extended Latin subset and other useful T.140 characters such as a
missing character that do not have Baudot equivalents, and the consensus
is to use an apostrophe for missing/untranslatable characters in Baudot,
right? So there would be more than specifying a simple scheme that
leverages the </font><font face="arial" size=2 color="#800080">V.18 Annex
A will not suffice, right?<br>
<br>
</font><font color="#800080">I am not sure if I am right here -- Fred
Lucas was probably going to put together a Baudot <-> T.140 Unicode
conversion table. Fred?<br>

<dd>I am not aware of any specific information about the 5-bit to Unicode

<dd>But it is straightforward, if you take the conversion tables from
V.18 Annex A, that goes between 5-bit and 7-bit T.50, and add your
knowledge that for all these 7-bit characters, the corresponding Unicode
character has the same value, just padded with 0 until it is 16
bits.</font>
<dd> <font face="arial" size=2 color="#0000FF">
<dd>Then you convert between Unicode UCS-16 and Unicode UTF-8 that
is used in T.140. I guess you have library functions for that. </font>

<dd>If you use V.18, the 5-bit to 7-bit is already there for you.</font>

<dd>The GSM implementation in the GTT feature must contain Unicode to
5-bit conversion, but I do not think it is explicitly specified anywhere
how it is done.</font>

<dd>It was said in the meeting that there is a way already defined to

this conversion. Can you point me to it?</font>
