What is the difference between UTF-8 and LATIN1?
What is the difference between UTF-8 and LATIN1?
They are different encodings (with some characters mapped to common byte sequences, e.g. the ASCII characters and many accented letters). UTF-8 is one encoding of Unicode with all its codepoints; Latin1 encodes less than 256 characters.
Is LATIN1 a subset of UTF-8?
Also, ISO-8859-1 is a subset of unicode (the “codepages” of the utf encodings), not UTF-8. What that means is that the first 256 characters in the codepage of ISO-8859-1 are the same characters as the first 256 characters in unicode.
What is encoding =’ latin1?
Latin-1, also called ISO-8859-1, is an 8-bit character set endorsed by the International Organization for Standardization (ISO) and represents the alphabets of Western European languages. This is because the first 128 characters of its set are identical to the US ASCII standard.
How do I change Postgres from LATIN1 to UTF8?
Convert a PostgreSQL database from LATIN1 to UTF-8
- Set up a replica base system in a VM.
- Export the production DB in its native encoding.
- Import the exported data into the VM and verify.
- Export the VM DB using UTF-8 encoding.
- Drop the DB, recreate it using UTF-8, import and verify.
- Rinse, repeat…
What are garbled characters?
Mojibake (文字化け; IPA: [mod͡ʑibake]) is the garbled text that is the result of text being decoded using an unintended character encoding. The result is a systematic replacement of symbols with completely unrelated ones, often from a different writing system.
What is Latin-1 string?
Is UTF-8 compatible with Latin-1?
No. Latin-1 is a subset of Unicode. Latin-1 and Unicode are both character sets. UTF-8 is one of several standard representations (or encodings) of Unicode the others being UTF-16, UTF-32 and GB18030.
What is latin1 in Python?
This is a type of encoding and is used to solve the UnicodeDecodeError, while attempting to read a file in Python or Pandas. latin-1 is a single-byte encoding which uses the characters 0 through 127, so it can encode half as many characters as latin1.
Why is my text not valid in UTF-8 or Latin-1?
Your original text is totally mangled, it’s not valid in UTF-8 or latin-1. It looks like someone’s taken some UTF-8 data, decoded it as latin-1, and then encoded it as utf-8 again. there’s your explanation.
Can I substitute Latin-1 encoded data where I think I am?
You’re not substituting latin-1 encoded data where you think you are. Not only that, but your replace could only have matched in the first place if the replace target was the utf-8 encoded byte sequence for ä interpreted as latin-1, i.e. \\303\\203\\302\\244.
Why is my text being sent in U+00E4 format?
It looks like whatever client you are using is confused about the text encoding; it’s sending utf-8 bytes as if they were latin-1, probably. Your update is substituting the octal bytes \\303\\244 which are the utf-8 encoding for “ä” (U+00E4).
What is the default encoding of the pgcluster template1 and template0 databases?
Incidentally, on an Ubuntu 12.04 box, the default encoding of the template1 and template0 databases on initial creation of the pgcluster had a default encoding of LATIN1. I had dropped the template1 db and created it afresh with an utf-8 encoding as you can see below.
