Bug report: wrong table sorting

How to reproduce:

1. execute the commands below
2. select database HeidiSQL_bugreport at left panel
3. go to right panel and order tables by name
4. you will find, that tables are not order alphabetically (see screenshot attached)

DROP DATABASE  HeidiSQL_bugreport;
CREATE DATABASE HeidiSQL_bugreport;
CREATE TABLE HeidiSQL_bugreport.`40AB_Abc` (
    `dummy` VARCHAR(32) NOT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;
CREATE TABLE HeidiSQL_bugreport.`2SN_beta` (
    `dummy` VARCHAR(32) NOT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;
CREATE TABLE HeidiSQL_bugreport.`2SN100_beta` (
    `dummy` VARCHAR(32) NOT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;
CREATE TABLE HeidiSQL_bugreport.`2SN100_gamma_3` (
    `dummy` VARCHAR(32) NOT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;
CREATE TABLE HeidiSQL_bugreport.`2SN100_alpha_1` (
    `dummy` VARCHAR(32) NOT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;
CREATE TABLE HeidiSQL_bugreport.`lorem` (
    `dummy` VARCHAR(32) NOT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;
CREATE TABLE HeidiSQL_bugreport.`ipsum` (
    `dummy` VARCHAR(32) NOT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;

Seems my sorting algorithm removes non-digits from names which start with a digit. If you do that virtually here, the names look as follows:

• 2
• 40
• 2100
• 21001
• 21003
• ipsum
• lorem

This is of course wrong.

Nice reproduction recipe by the way!

Could you post this in the tracker please?
