About sequence checking and replacing invalid characters in South Asian text
The feature or some of the options described in this Help topic are only available if support for the appropriate South Asian language is enabled through Microsoft Office Language Settings.
South Asian languages refer to the written languages used in India, Thailand, and other countries in southern Asia. These languages use a combination of syllabic and phonemic characters as well as diacritics.
To assist you in correctly entering South Asian language characters in your publication, Microsoft Publisher can automatically check the text for you using a feature called Sequence Checking. Also, you can have Publisher make logical substitutions for you by using Type and Replace, a complementary feature.
Sequence Checking can be used by itself or in combination with Type and Replace. When Sequence Checking only is selected, Publisher will not allow an invalid character to be typed at the insertion point. If Type and Replace is also selected, Publisher will insert or replace an existing character to make a valid sequence.
When Sequence Checking is selected, there are some text entry considerations:
- In Thai, you cannot type markings such as tone marks and upper and lower vowels independent from the character they are associated with. If you need to type these markings independently, you must turn off Sequence Checking. Also, leading vowels must be followed by a consonant that may or may not include upper vowels. It is not possible to have lower vowels together with leading vowels and a consonant.
- In Vietnamese, only one tone mark is allowed on each vowel, and it can only be typed after the vowel. Typing a tone mark after a consonant will not insert the character in the publication.
