Did you set those up on the 'numbers' tab? You need to modify the settings on the 'money' tab of the locale settings in KDE which should be picked up by KMyMoney.

Yes, I set up both tab numbers and money. Then I click Apply and restart my computer also, but there isn't any changes.

*** Bug 300070 has been marked as a duplicate of this bug. ***

It could be that KMyMoney will not allow a space as numbers separator, need to check this.

Is there any progress on this issue ?

I'm french, and I used to have a space as group separator for numbers. Currently, kmymoney 4.8.0 (running with KDE 4.14.29 on Linux Arch 4.9.11-1) is not able to be configured this way.

Thx.

According to https://docs.oracle.com/cd/E19455-01/806-0169/overview-9/index.html the affected languages are Canadian, German, Dansk, Finish, French and Swedish.

Setting thousand separator is handled by MyMoneyMoney::setThousandSeparator() which simply ignores ' ' as separator. Changing is really simple by removing some lines inside the mentioned method.

The much bigger task is to verify that removing the former "ignore" behavior does not introduce unwanted regressions.

(Candian French and Canadian English are two separate languages)
Does this only affect KMM, or is there anything at a higher level in KDE which should be changed also?

This does only affect KMM only. I kmm main function the KDE thousand separator system settings is copied into kmm, see below

main.cpp
138: // setup the MyMoneyMoney locale settings according to the KDE settings
139: MyMoneyMoney::setThousandSeparator(KGlobal::locale()->monetaryThousandsSeparator()[0]);

Because ' ' as thousand separator is ignored the whole application does not know anything about this value except the cases where KGlobal::locale()->monetaryThousandsSeparator() is used directly, which is 
1. MyMoneyQifProfile::clear()
2. kMyMoneyMoneyValidator::validate()

An interesting location is inside GncObject::hide() 
... 
      case MONEY2:
        in = MyMoneyMoney(data);
        if (data == "-1/0") in = MyMoneyMoney();
        mresult  = MyMoneyMoney(m_moneyHideFactor) * in;
        mresult.convert(10000);
        MyMoneyMoney::setThousandSeparator(' ');
        result = mresult.formatMoney("", 2);
        break;

Because ' ' is converted to '', which means no thousand separator this could be rewritten to 

        result = mresult.formatMoney("", 2, false);

The third parameter is a value for showThousandSeparator.

I'm talking about code because the task is to inspect any call of formatMoney() if it falls into one of the following category: 

1. used for debug output
2. used for gui output
3. used for further processing
4. used for file export

Category 1. and 2. are uncritical (from my current knowledge) but the other need to be inspected  and optional fixed like the mentioned example.

<offtopic>Refactoring the above mentioned code fragment also fixes an additional bug: Because the original thousand separator is not saved and restored (as it is done in the qif reader), this piece of code kills the thousand separator in the whole application until kmymoney will be been restarted.</offtopic>

- formatMoney(..., false) -> safe case
- formatMoney(..., true)  -> not used
- all calls in test code

MyMoneyEdit cares about only allowing the configured language specific thousand separators (tested with de and en_us language)

Because master diverged too much from 4.8 I'm going to recreate similar patch(es) for 4.8

You fixed this in CsvWriter::writeTransactionEntry() but not in  CsvWriter::writeSplitEntry(), see https://cgit.kde.org/kmymoney.git/tree/kmymoney/plugins/csv/export/csvwriter.cpp#n256

BTW: It looks that removing this replacement, which intention was to fixes clash with field separator, introduces a new bug resulting into invalid csv file in case the memo field contains the field delimiter.
