After TW2.7.0 was released, it was reported that it was failing to pass a test for "valid UTF-8" encoding, due to the presence of a single byte 0xFF (which is outside the 0x00-0x7F range for single-byte characters... i.e. 7-bit ASCII encoding). By using a binary/hex editor to search the content of the file, the errant byte was located within a quoted string used as a literal parameter being passed in function deep within the jQuery 1.8.1 code. Jeremy and I did a number of experiments to attempt to isolate the cause of the introduction of the errant byte (e.g., was it a result of a one-time build error or a problem with with TW5 build tools, etc.). As part of this investigation, we decided to see if the *current* revision of jQuery contained the same quoted string of binary values... or even anything similar. What we found is that jQuery1.8.3 had actually replaced the content of the errant quoted string parameter, and now uses "\U..." syntax to represent the same binary values that were previously embedded directly. Thus, although we didn't actually determine the origin of the problem, we did find a robust solution by updating the embedded jQuery library from v1.8.1 to v1.8.3, thereby bypassing the problem entirely. (I suspect that other users of jQuery may have run into similar issues, prompting the change to their implementation). The good news is that, with the updated jQuery library in place, the assembled TW2.7.1b1 file now passes the normal 'validity checks' for UTF-8 encoding. -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
