>    Affects Versions: 1.14.0, 1.15.0, 1.16.0, 1.17.0

> Strange results from TO_CHAR function when using different LOCALE.
> {code:java}
> SELECT TO_CHAR((CAST('2008-2-23' AS DATE)), 'yyyy-MMM-dd') FROM (VALUES(1));
> 2008-Feb-23 (in documentation (en_US.UTF-8)) 
> 2008-févr.-2 (fr_FR.UTF-8)
> {code}
> surprisingly by adding a space ('yyyy-MMM-dd ') (or any character) at the end of the format  the result becomes correct (so there is no problem when format a timestamp with 'yyyy MMM dd HH:mm:ss')
> {code:java}
> SELECT TO_CHAR(1256.789383, '#,###.###') FROM (VALUES(1));
> 1,256.789 (in documentation (en_US.UTF-8)) 
> 1 256,78 (fr_FR.UTF-8)
> {code}
> Even worse results can be achieved
> {code:java}
> SELECT TO_CHAR(12567,'#,###.###');
> 12,567 (en_US.UTF-8)
> 12 56 (fr_FR.UTF-8)
> {code}
> Again, with the add of a space/char at the end we get a better result.
> I don't have tested all the locale, but for the last example, the result is right with de_DE.UTF-8 : 12.567
> The situation is identical in 1.14
