feature-request: add maxLength, maxSize attributes to string resources and fail at compilation if a string is too long

Short feature-request:

Please add a new attribute to string resources to let the compiler know the maximum length * of strings, and enforce it in such a way that if a longer string is present (either because I edited the string or because it's a translation) then fail at compile time.

i.e:

resources/strings.xml:
<string id="stepsUnits" maxLength=16>steps</string>

resources-tha/strings.xml:
<string id="stepsUnits">ขั้นตอน</string>

*) I think it would make sense to give the developer to possibility to set a constraint to either the character count or the byte size or both. The idea is that for cases like the above I would need to be able to set a maxSize in bytes, but in many other cases where the constraint comes from a UI point of view it would make sense to have a maxLengh in characters.

Long story: I got lot of complaints about a strange crash in my app. Today I realized that it only happens in Thai language devices. This helped me to find the bug:

var stepsUnits = WatchUi.loadResource(Rez.Strings.stepsUnits) as String;
mStepsActivityField = session.createField("steps", 0, FitContributor.DATA_TYPE_UINT32, { :mesgType => FitContributor.MESG_TYPE_SESSION, :units => stepsUnits });

And the Thai language translation is:

<string id="stepsUnits">ขั้นตอน</string>

According to the documentation :units is at least 16 bytes. So now I found out the hard way that:
- Thai either 4 bytes / character
- that the 16 bytes includes the terminating 0 of the string.
