UnicodeFuzzySearch: Add parenthesis around the function call.

`chr` or `hex` was eating up everything in the function and treating them all as parameters. Because of that, it results into:

```perl
{
    symbol => "...",
}
```

Instead of:

```perl
{
    symbol => "...",
    code => "...",
    name => "...",
}
```
