Hi @bertfrees, I now understand this rule. However, the user can't check the effect. Is there any condition about the liblouis version to run the rule?

Hi @bertfrees, The user copy the two rules into zh-tw.ctb of his NVDA. ``` attribute FRACTION \x2150\x2151\x2152\x2153\x2154\x2155\x2156\x2157\x2158\x2159\x215A\x215B\x215C\x215D\x215E noback context _1$d[%FRACTION] @456-1456*@456-3456 ``` Then, the braille display doesn't work. So, I...

To merge [#1244](https://github.com/liblouis/liblouis/pull/1244) may close this issue. However, I think there would be better set of testcases to the rule: `noback context [%FRACTION] @1456*@3456` It means a default case. If...

I use ``` include zh-tw.ctb ``` , rather than ``` include tables/unicode.dis include tables/en-us-comp8.ctb ``` to generate the result in the initial comment. What is wrong?

@bertfrees, > I just added the YAML test so that people can reproduce your issue. Because the table that you provided was incomplete. en-us-comp.ctb or zh-tw.ctb doesn't make a difference....

@bertfrees, I worried that the reason might be my misunderstanding about the liblouis syntax, so I didn't write the YAML here. Now, I submit a complete version of my original...

For example, we should describe a cubic polynomial as follows. ``` f(x)=a₀+a₁x+a₂x²+a₃x³ ⠋⠷⠭⠾⠿⠁⠰⠴⠐⠬⠁⠰⠂⠐⠭⠬⠁⠰⠆⠐⠭⠘⠆⠐⠬⠁⠰⠒⠐⠭⠘⠒⠐ ``` For example, we should describe the recursion of Fabonacci numbers as follows. ``` fₖ=fₖ₋₁+fₖ₋₂ ⠋⠰⠅⠐⠿⠋⠰⠅⠤⠂⠐⠬⠋⠰⠅⠤⠆⠐ ```
