I think the simplest course of action is just require the character before to be Hebrew; that is a sufficient limitation on usage.<br><br clear="all">Mark<br>

I totally agree with Ken's analysis of Gershayim usage, and with his<br>
simplified pseudo-code.<br>
<br>
However, I seem to remember somebody mentioning using Gershayim at the<br>
boundary between preceding Hebrew letters and succeeding letters from<br>
another script. Personally, I see no need for this, and such a label<br>
would probably be disallowed anyway by the rules for Bidi domain names.<br>
Still, if anybody thinks there is such a use case, he/she should speak<br>
now.<br>

Patrik,<br>
<br>
With my general concerns about the pseudo-code<br>
out of the way, I'll now take up the issue of<br>
how to express the rule set for A.8. HEBREW PUNCTUATION<br>
GERSHAYIM.<br>
<br>
Currently, the relevant parts of the Appendix state:<br>
<br>
Overview:<br>
The script of the preceding character and the subsequent<br>
character, if any, MUST be Hebrew.<br>
...<br>
Rule Set:<br>
False;<br>
If Script(Before(cp)) .eq. Hebrew And<br>
LastChar .eq. cp Then True;<br>
If Script(Before(cp)) .eq. Hebrew And<br>
Script(After(cp)) .eq. Hebrew Then True;<br>
<br>
First let's consider what the appropriate context for<br>
the gershayim are in ordinary Hebrew text usage.<br>
<br>
The gershayim are used to indicate that a word is to<br>
be read as an acronym, rather than as a regular word.<br>
Its position in the acronym is between the next-to-last<br>
and the last letters of the non-inflected form of the<br>
acronym. What that means is that it will be preceded<br>
by one or more letters, and will be followed by at<br>
least one letter (and possibly more, if the acronym is<br>
inflected). But it shouldn't occur at the beginning or<br>
end of a word.<br>
<br>
The gershayim are also used to mark numerical usage of<br>
Hebrew letters, but in the case where a number is<br>
represented by two or more Hebrew numerals. So again,<br>
in that case, it would be internal to the numeral,<br>
and not at the beginning or end.<br>
<br>
Then there is a usage to indicate transliteration of<br>
a foreign word -- but again the position is word-internal,<br>
between the next-to-last and the last character of the<br>
word.<br>
