I have Sogou Pinyin on Ubuntu and things work fine, but I haven't been able to figure out how to type Pinyin with tone marks, e.g. 'mǎ', etc.
I've looked into the settings but found no option like that. I've searched online (in Chinese) but results I get show that Windows Sogou has a very different, more comprehensive menu structure with more options. The Ubuntu version seems like a dumbed down version of that, nothing close.
I've tried typing U + Unicode, e.g. U+0101 for 'ā' but that's a hassle. Copying from an online tool is also cumbersome, I have to type a lot of tone marked pinyin.
Has anyone run into this issue?
