In Dutch (in Belgium as in the Netherlands), when you type "'s" or "'t" in sentences like: "Ik ben 's morgens opgestaan", the apostrophe is changed into an opening quote by the autocorrect feature, which is incorrect and requires a manual correction.
There are two cases possible:
a) The buggy behaviour happens when Tools > AutoCorrect Options... > Localized Options > Single Quotes > Enabled is checked.
This behaviour can be corrected by editing the file DocumentList.xml contained in the ZIP containers as explained below:
b) When the Single Quotes > Enabled option above is not checked, there is no buggy behaviour, but it is still recommended to autocorrect the introduction of the U+0027 character (apostrophe) into the U+02BC character, for aesthetical reasons.
So two rules must be added for "'s" and two for "'t", in order the changes to work in both cases, a) and b).
Therefor, the changes I suggest for the DocumentList.xml file inside the ZIP containers mentioned above consist in adding four "block-list:block" nodes on the right place into it with next content:
<block-list:block block-list:abbreviated-name="'s" block-list:name="ʼs"/><block-list:block block-list:abbreviated-name="'t" block-list:name="ʼt"/><block-list:block block-list:abbreviated-name="‘s" block-list:name="’s"/><block-list:block block-list:abbreviated-name="‘t" block-list:name="’t"/>
Sounds like a reasonable suggestion -> NEW.
