Hi, About P1 in UBA *P1. Split the text into separate paragraphs. A paragraph separator is kept with the previous paragraph. Within each paragraph, apply all the other rules of this algorithm.* Here, what does paragraph mean? which symbols can *Split the text into separate paragraphs? I think

Hi, I have read the reference code for BIDI algorithm implement in http://www.unicode.org/Public/PROGRAMS/BidiReferenceCpp/ I'm confused about some codes in Bidi.cpp. Before determining embedding levels for characters, assign directional types like this // assign directional types

I'd like to implement the combination of thai and decanagrari scripts using vector font. But I have no idea about it. How do i adjust the position of the combined glyph? Could anyone give some advices or references? Thanks a lot!

Hi all, I have a question about the BIDI algorithm implementation. Bidi algorithm describe that one must resolving embedding level in a paragraph before break paragraph into lines. I don't understand why. Should we firstly break paragraph into lines and remember the paragraph level, and then

Yes, this is the algorithm I have read. http://unicode.org/reports/tr9/ But I don't know why user must take a paragraph as a unit to determine the embedding levels. Why can't i shape the text first and then wrapping the line, and determining the embedding levels for characters within a line.
