There are some very rare and hard-to-debug cases involving cut-n-paste from a web browser. Some web browsers sometimes insert .. weird whitespace UTF-8 characters, that (a) are invisible -- they're whitespace, and (b) cause scheme/python/c++/word-processor to mis-behave and act badly. Its very hard to debug .. because .. its whitespace. You can find them with tools like hexdump, and search for any non-ascii characters. Now, guile/python/c++/etc are "100%" UTF-8 safe, and work fine. But the weird whites-ace means that variable-names or other code might not be what you think it is... --linas -- cassette tapes - analog TV - film cameras - you -- You received this message because you are subscribed to the Google Groups "opencog" group.
