# PostgreSQL ASCII folding
|
|
|
|
Reasonably fast ASCII folding functions (based on [Lucene asciifolding filter](https://lucene.apache.org/core/4_0_0/analyzers-common/org/apache/lucene/analysis/miscellaneous/ASCIIFoldingFilter.html)) for PostgreSQL
|
|
|
|
*Example:*
|
|
```
|
|
postgres=# SELECT asciifold('Hello, ⒩ᴐⱤú⒴⁈～!');
|
|
asciifold
|
|
----------------------
|
|
Hello, (n)ORu(y)?!~!
|
|
(1 row)
|
|
```
|
|
|
|
UTF8 input string is not sanitized (invalid UTF8 might lead to undefined behavior)
|
|
|
|
### Compiling from source (CMake)
|
|
|
|
```bash
|
|
apt install postgresql-server-11-dev
|
|
cmake .
|
|
make
|
|
```
|
|
|
|
