[FIX] core: use non-breaking space for currency symbol

In some languages and layout the currency symbol might be wrapped in a separate
line, which is not acceptable from accounting point of view. Fix it by replacing
space with a special symbol.

STEPS for v15:
* install MX localization;
* create a Spanish speaking customer
* generate a pdf:
1) Create quotation with products
2) Add IVA 16%tax
3) print a report

BEFORE: the currency symbol is incorrectly displayed on a separate line
AFTER:  currency symbol is always with the amount
