Issues with Thai wrapping

Question

I have been trying out TLF with various spark and FTE components, but unfortunately have been having issues with line-wrapping in Thai. It doesn't seem to break in between words.
For example, I have tried a spark TextArea/RichText/RichEditableText and set locale for the components to 'th_TH'.
Four Questions:
1) Should Thai be working correctly?
2) Does setting locale matter at all?
3) Do FTE & TLF components have the same bidi/international capabilities? Or is TLF more robust? (For example, should thai/arabic/etc work the same in both a FTE/TLF component?)
4) When highlighting Thai/Arabic/Hebrew in certain components, the characters shift all around with the cursor. Is this a bug?
Thanks a lot

Hi bogmead,
There is a attribute to control line wrapping in TLF. The attribute should be set on flashx.textLayout.element.TextFlow(<s:TextFlow> in Flex) or some of its child elements, rather than flex components.
<xs:attribute name="breakOpportunity" type="xs:enumeratedString" default=" auto"/>
Controls where a line can validly break.
Valid values include:
• auto Line breaking opportunities are based on standard Unicode character properties, such as breaking between words and on hyphens.
• any Indicates that the line may end at any character. This value is typically used when Roman text is embedded in Asian text and it is desirable for breaks to happen in the middle of words.
• none No characters in the range are treated as line break opportunities.
• all All characters in the range are treated as mandatory line break opportunities, thereby creating one character per line. This value is useful for creating effects like text on a path.
A range is a continuous group of characters that have none applied. Therefore, selecting “one of” and applying none, results in a range of characters starting with “o” and ending with “f” that have none applied and will not get any line breaks inside the range.
