RE: Re: emacs + unicode + hebrew + bidi

[Bourgneuf Francois]

Just a precision, in arabic and hebrew both text and numbers are written right to left.

In western languages text is written left to right and numbers right to left.

You can't tell the value of the left digit of a number if you havent read how many digit are at his right.

We solve additions from the right to the left.

Thank you, but unforunatly, it is not a solution -
Hebrew is not simple right to left
its a BI-Directional. Then text is written from rtl the number ltr, what
about the punctuation signs, spaces and etc..
the bi-di code is very complex
