> The Calcite runtime uses Java to parse values when converting strings to
> other types. As a result, the runtime accepts Java constructs which are not
> legal in SQL. Examples:
>
> ||Cast||String||Java rule that accepts it||Constant||
> |DOUBLE, REAL|{{{}'1.5d'{}}}, {{'1.5f'}}|type suffix on a Java number|1.5|
> |DOUBLE, REAL|{{'0x1p3'}}|hexadecimal floating-point number|8.0|
> |INT types|{{'٧'}} (U+0667, Arabic-Indic 7)|{{Character.digit}} accepts any
> Unicode digit|7|
> |BOOLEAN|{{'falſe'}} (U+017F, long s)|{{equalsIgnoreCase}} upper-cases {{ſ}}
> to {{S}}|FALSE|
