Can confirm absence of blue dots for space characters within text although correspondent option is enabled in Formatting Aids options. Downgrade to 5.2.5 resolves issue.

I've noticed on last attachment that tab symbols are centred, but also that MacOs version is more recent than mine, that is 10.8.5. So the behavior is different among versions of MacOs.
Comment 5 Alex Thurgood 2017-02-27 08:25:48 UTC
Confirming both on

Build ID: 7074905676c47b82bbcfbea1aeefc84afe1c50e1
CPU Threads: 2; OS Version: Mac OS X 10.12.3; UI Render: default; Layout Engine: new; 
Locale: fr-FR (fr_FR.UTF-8); Calc: group

The space characters are not displayed.

Tabs and line feed characters are displayed too high (above the centre of the line on which text is written).

@Khaled : anything to do with the recent changes in core text display code ?
