The "_" character in the geofile name breaks the launch

[jameszeroX]

完整性要求

• 我读完了 issue 模板中的所有注释，确保填写符合要求。
• 我保证阅读了文档，了解所有我编写的配置文件项的含义，而不是大量堆砌看似有用的选项或默认值。
• 我提供了完整的配置文件和日志，而不是出于自己的判断只给出截取的部分。
• 我搜索了 issues, 没有发现已提出的类似问题。
• 问题在 Release 最新的版本上可以成功复现

描述

If the name of the geo file contains the character "_", the proxy does not start. If you replace the "_" with any other character, the launch is successful

重现方式

The problem is only with xray 26.1.13

[nebulosa2007]

In my situation there is no problem with underscore (tested already with other dat files) but with geosite file. Errors in log are identical

Please see MHSanaei/3x-ui#3675 I already described here

这里就那么水灵灵拿下划线当组合分隔符了 我写进程名路由还得考虑半天的魔法字的歧义问题 然后这个下划线刚好还是大量改版geo文件喜欢用的(eg. geoip_IR.dat) 就炸了 嘛 反正没人审(

[RPRX]

@Fangliding 你把它改一下还是，或者先把那几个 commit 给 revert 了吧，那个伊朗开发者现在联系不上

[Fangliding]

我也不知道怎么改 我也没细看 如果要revert的话应该是 c715154309e41e759f544edd3667889e257fb3af 961c352127f32c04034a88d021a683e6a80eac20 mmap那个应该问题不大

[RPRX]

@Fangliding 那就先开个 PR 把这俩给 revert 了吧，其它的等 @hossinasaadi 上线了再说

mmap 那个就是读取文件应该没啥问题，后面他改的那个 test 也是

[RPRX]

不过 @H1JK 说 Windows 上也能 mmap #5480 (comment)

要不就先把那四个 commit 全 revert 了

[RPRX]

毕竟以后有了 #5505 ，前面的这些小优化感觉都没啥必要了

[RPRX]
