|
|
1162 | #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x) |

1201 | =head3 Character widths are not correct. |
|
|
1202 | |
|
|
1203 | urxvt uses the system wcwidth function to know the information about |
|
|
1204 | the width of characters, so on systems with incorrect locale data you |
|
|
1205 | will likely get bad results. Two notorious examples are Solaris 9, |
|
|
1206 | where single-width characters like U+2514 are reported as double-width, |
|
|
1207 | and Darwin 8, where combining chars are reported having width 1. |
|
|
1208 | |
|
|
1209 | The solution is to upgrade your system or switch to a better one. A |
|
|
1210 | possibly working workaround is to use a wcwidth implementation like |
