UTF8 ובסיסי נתונים MySQL Database

זה כבר כמה זמן אני מעוניין לכתוב על ניהול נכון של Encoding בבניית אתרי אינטרנט. אנשים נוטים לבצע טעויות רבות ולא מבינים את המשמעות שבין UTF-8 לבין תקני ISO ותקנים של Windows כגון Windows-1255. הבעיות מופיעות בבחירה לא נכונה של Charset הן בבניית העמוד והן בשמירה ב - Database.

לצערי אין לי את הזמן כרגע, אבל אני בוודאי שעוד אחזור לכך ואסביר את כל שלבי ה - Encoding מה - Datbase דרך ה - Webserver וכלה בדף ה- HTML והתצוגה בדפדפן.

כרגע אני משתף קוד קצר ל - mysql שימיר לנו שדות טקסט ששמרנו בהם עברית ב - Charset latin1 ל - UTF8.


ALTER TABLE files ADD COLUMN temp TEXT CHARACTER SET utf8 COLLATE utf8_general_ci AFTER text; -- add the temp column

UPDATE files SET temp=CONVERT(CONVERT(text USING binary) USING utf8); -- convert the data to the new column

ALTER TABLE files DROP COLUMN text; -- drop original column

ALTER TABLE files CHANGE temp text TEXT CHARACTER SET utf8 COLLATE utf8_general_ci; -- rename temp column

Change hebrew / or other charset inside MySQL to UTF-8.

Bypassing the error by "go get" "tls: failed to verify certificate: x509: certificate signed by unknown authority"

When I was trying to download dependencies for my go project in an old Ubuntu machine I was getting this error all the time: "go: gopkg.in/alexcesaro/quotedprintable.v3@v3.0.0-20150716171945-2caba252f4dc: Get "https://proxy.golang.org/gopkg.in/alexcesaro/quotedprintable.v3/@v/v3.0.0-20150716171945-2caba252f4dc.mod": tls: failed to verify certificate: x509: certificate signed by unknown authority" Which the main part of it was go get failing to authenticate: " tls: failed to verify certificate: x509: certificate signed by unknown authority " I tried many things but couldn't make it work until I found the way: export GOINSECURE="proxy.golang.go" This will tell go get to ignore certification validity. Then export GOPROXY=direct This will tell go get to by pass proxy Then git config --global http.sslverify false And only after those I could run again: go get And it worked
