mysql - Is it safe to update tables from latin1 to utf8 -


whilst doing checking client see if site still functioning found random page contained bunch of weird characters ¿½.

i think has tables having latin1 encoding instead of utf-8. seeing no other pages affected use same table there error. did check if text safe , making sure clean text.

so have 2 questions, main 1 being safe update 1 table utf8 , if not causes error , wondered why affects 1 page. (side note website built using typo3)
ofcourse have live example's links are:
site 1: weird text characters
site 2: same table, no weird characters

ultimately client connecting database decides how encodings handled; that's known connection encoding. whatever encoding text stored in mysql, converted on fly to/from client's connection encoding. such, changing underlying column's storage utf8 doesn't affect anything.

however, in won't "fix" anything. characters still garbage. you'll have convert actual characters correct data. otherwise you'll have "¿½" stored encoded utf8 instead of "¿½" stored encoded latin1. , changing characters will affect other client has been doing wrong far, client side needs fixed @ same time.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
