Inter-script spacing #65

Open xfq opened 9 months ago

xfq commented 9 months ago

There is extra spacing between Chinese/Japanese characters and Western characters or European numerals. Is there similar behaviour for the scripts that also do not use space to separate words (like Balinese, Batak, Javanese, Khmer, Lanna, Lao, Myanmar, and Thai)?

If so, how much extra spacing?

In Thai writing, we have space between

Thai character and non-Thai character
Alphabet and numeral
Character and certain symbols

But in current practice, we just explicitly place a "space" character there. The spacing is not from typesetting.

For justified typographic alignment, these spaces between different groups of characters are opportunities for space adjustment.

They can be sometimes opportunities for line break as well. But not always.
