The encoding setting "utf8" (i.e. utf8.def of the "inputenc" package) supports only a small subset of unicode characters (mainly latin). It works e.g. well with German umlauts and other Latin extensions. However, these are also well supported by LyX internal conversion rules as defined in the "unicodesymbols" definition file. "utf8x" (the interface to the "ucs" package) might be a solution for some characters not "known" by LyX (e.g. for some accented Greek characters used in polytonic Greek). Günter

Erase the last half and see if the problem persists. If it does, erase the now remaining last half and so on. Pretty soon you should have only a small portion left that you an inspect maually. Five times would reduce 32 pages to just one page. regards, Christian -- Christian Ridderström, +46-8-768 39 44http://www.md.kth.se/~chr

Programs that relied on unicode == 16 bit (including LaTeX) have problems now with higher unicode numbers. FYI, LyX uses utf32 internally, that is the 32 bit version, and utf8 as its file format.

I know nothing about unicode, so I'd need to be brought up to speed on that before writing the program. I assume unicode is a 16 bit representation of characters.

Actually, changing the encoding to utf8 will most probably *not* help (as utf8 is very limited in the range of supported characters). You could try changing to utf8x. This might help - maybe just by a more specific error message. Günter

It is very tedious by eye... In recent versions (1.5.5, if not earlier), you can find it by opening "View->Source Code". The problematic characters are highlighted in red. Jürgen
Finding "Bad" characters
If all goes well the cursor should be at the bad characters when the error pops up. Do you have the latest 1.5-version? Ligatures (which are very hard to see) are fixed there IIRC. Also a good thing is to check your formulas. Anders
Finding "Bad" characters
Hi, I have a relatively large lyx document that does not compile. The error message is: "Some characters of your document are probably not representable in the chosen encoding. Changing the document encoding to utf8 could help." The problem is most likely caused by some characters that I forgot to change after pasting from OOwriter. Is there any way to find those characters? It is very tedious by eye...
